Scanning Documents into Data Lakes via Tesseract, Python, OpenCV and Apache NiFi Source: https://github.com/tspannhw/nifi-tesseract-python There are many awesome open source tools available to integrate with your Big Data Streaming flows. Take a look at these articles for installation and why the new version of Tesseract is different. I am officially recommending Python 3.6 or newer. Please don't use Python 2.7 if you don't have to. Friends don't let friends use old Python. Tesseract 4 with Deep Learning https://www.learnopencv.com/deep-learning-based-text-recognition-ocr-using-tesseract-and-opencv/ Github: https://github.com/spmallick/learnopencv/tree/master/OCR For installation on a Mac Laptop: brew install tesseract --HEAD pip3.6 install pytesseract brew install leptonica Note: if you have tesseract already, you may need to uninstall and unlink it first with brew. If you don't use brew, you can install another way. Summary Execute the run.sh (https://github.com/tspannhw/nifi-tesseract-python/blob/master/pytesstest.py) . It will send a MQTT message of the text and some other attributes in JSON format to the tesseract topic in the specified MQTT broker. Apache NiFi will read from this topic via ConsumeMQTT The flow checks to see if it's valid JSON via RouteOnContent. We run MergeRecord to convert a bunch of JSON into one big Apache Avro File Then we run ConvertAvroToORC to make a superfast Apache ORC file for storage Then we store it in HDFS via PutHDFS Running The Python Script You could have this also hooked up to a scanner or point it at a directory. You could also have it scheduled to run every 30 seconds or so. I had this hooked up to a local Apache NiFi instance to schedule runs. This can also be run by MiniFi Java Agent or MiniFi C++ agent. Or on demand if you wish. Sending MQTT Messages From Python # MQTT client = mqtt.Client() client.username_pw_set("user","pass") client.connect("server.server.com", 17769, 60) client.publish("tesseract", payload=json_string, qos=0, retain=True) You will need to run: pip3 install paho-mqtt Create the HDFS Directory hdfs dfs -mkdir -p /tesseract Create the External Hive Table (DDL Built by NiFi) CREATE EXTERNAL TABLE IF NOT EXISTS tesseract (`text` STRING, imgname STRING, host STRING, `end` STRING, te STRING, battery INT, systemtime STRING, cpu DOUBLE, diskusage STRING, memory DOUBLE, id STRING) STORED AS ORC LOCATION '/tesseract'; This DDL is a side effect, it's built by our ORC conversion and HDFS storage commands. You could run that create script in Hive View 2, Beeline or another Apache Hive JDBC/ODBC tool. I used Apache Zeppelin since I am going to be doing queries there anyway. Let's Ingest Our Captured Images and Process Them with Apache Tika, TensorFlow and grab the metadata Consume MQTT Records and Store in Apache Hive Let's look at other fields in Zeppelin Let's Look at Our Records in Apache Zeppelin via a SQL Query (SELECT *FROM TESSERACT) ConsumeMQTT: Give me all the record from the tesseract topic from our MQTT Broker. Isolation from our ingest clients which could be 100,000 devices. MergeRecord: Merge all the JSON files sent via MQTT into one big AVRO File ConvertAVROToORC: converts are merged AVRO file PutHDFS Tesseract Example Schema in Hortonworks Schema Registry TIP: You can generate your schema with InferAvroSchema. Do that once, copy it and paste into Schema Registry. Then you can remove that step from your flow.

Using Apache MXNet GluonCV with Apache NiFi for Deep Learning Computer Vision Source: https://github.com/tspannhw/OpenSourceComputerVision/ Gluon and Apache MXNet have been great for deep learning especially for newbies like me. It got even better! They added a Deep Learning Toolkit that is easy to use and has a number of great pre-trained models that you can easily use to do some general use cases around computer vision. So I have used a simple well-documented example that I tweaked to save the final image and send some JSON details via MQTT to Apache NiFi. This may sound familiar: https://community.hortonworks.com/articles/198912/ingesting-apache-mxnet-gluon-deep-learning-results.html GluonCV makes this even easier! Let's check it out. Again let's take a simpmle Python example tweak it, run it via a shell script and send the results over MQTT. See: https://gluon-cv.mxnet.io/build/examples_detection/demo_ssd.html#sphx-glr-build-examples-detection-demo-ssd-py Python Code: https://github.com/tspannhw/UsingGluonCV/tree/master This is the Saved Annotated Figure Simple Apache NiFi Flow to Ingest MQTT Data from GluonCV example Python and Store to Hive and Parquet and HBase. A simple flow: ConsumeMQTT InferAvroSchema RouteOnContent MergeRecord (convert batches of json to single avro) ConvertAvroToORC PutHDFS PutParquet PutHbaseRecord Again Apache NiFi generates a schema for us from data examination. There's a really cool project coming out of New Jersey that has advanced schema generation looking at tables, I'll report on that later. We take it add, save to Schema Registry and are ready to Merge Records. One thing you may want to add is to turn regular types from: "type": "string" to "type": ["string","null"]. Schema { "type": "record", "name": "gluoncv", "fields": [ { "name": "imgname", "type": "string", "doc": "Type inferred from '\"images/gluoncv_image_20180615203319_6e0e5f0b-d2aa-4e94-b7e9-8bb7f29c9512.jpg\"'" }, { "name": "host", "type": "string", "doc": "Type inferred from '\"HW13125.local\"'" }, { "name": "shape", "type": "string", "doc": "Type inferred from '\"(1, 3, 512, 910)\"'" }, { "name": "end", "type": "string", "doc": "Type inferred from '\"1529094800.88097\"'" }, { "name": "te", "type": "string", "doc": "Type inferred from '\"2.4256367683410645\"'" }, { "name": "battery", "type": "int", "doc": "Type inferred from '100'" }, { "name": "systemtime", "type": "string", "doc": "Type inferred from '\"06/15/2018 16:33:20\"'" }, { "name": "cpu", "type": "double", "doc": "Type inferred from '23.2'" }, { "name": "diskusage", "type": "string", "doc": "Type inferred from '\"112000.8 MB\"'" }, { "name": "memory", "type": "double", "doc": "Type inferred from '65.8'" }, { "name": "id", "type": "string", "doc": "Type inferred from '\"20180615203319_6e0e5f0b-d2aa-4e94-b7e9-8bb7f29c9512\"'" } ] } Example JSON {"imgname": "images/gluoncv_image_20180615203615_c83fed6f-2ec8-4841-97e3-40985f7859ad.jpg", "host": "HW13125.local", "shape": "(1, 3, 512, 910)", "end": "1529094976.237143", "te": "1.8907802104949951", "battery": 100, "systemtime": "06/15/2018 16:36:16", "cpu": 29.3, "diskusage": "112008.6 MB", "memory": 66.5, "id": "20180615203615_c83fed6f-2ec8-4841-97e3-40985f7859ad"} Table Generated CREATE EXTERNAL TABLE IF NOT EXISTS gluoncv (imgname STRING, host STRING, shape STRING, end STRING, te STRING, battery INT, systemtime STRING, cpu DOUBLE, diskusage STRING, memory DOUBLE, id STRING) STORED AS ORC LOCATION '/gluoncv' Parquet Table create external table gluoncv_parquet (imgname STRING, host STRING, shape STRING, end STRING, te STRING, battery INT, systemtime STRING, cpu DOUBLE, diskusage STRING, memory DOUBLE, id STRING) STORED AS PARQUET LOCATION '/gluoncvpar' Reference: https://gluon-cv.mxnet.io/ https://gluon-cv.mxnet.io/build/examples_detection/index.html https://medium.com/apache-mxnet/gluoncv-deep-learning-toolkit-for-computer-vision-9218a907e8da ...

Integrating Keras (TensorFlow) YOLOv3 Into Apache NiFi Workflows For this article I wanted to try the new YOLOv3 that's running in Keras. Out of the box with video streaming, pretty cool: git clone https://github.com/qqwweee/keras-yolo3 wget https://pjreddie.com/media/files/yolov3.weights python convert.py yolov3.cfg yolov3.weights model_data/yolo.h5 python yolo.py See: https://github.com/qqwweee/keras-yolo3 My article on Darknet original YOLO v3 is here: https://community.hortonworks.com/articles/191259/integrating-darknet-yolov3-into-apache-nifi-workfl.html Example JSON Output { "boxes" : "Found 8 boxes for img", "class7" : "diningtable", "score7" : "0.7484486", "left7" : "636", "right7" : "1096", "top7" : "210", "bottom7" : "693", "class6" : "sofa", "score6" : "0.31372178", "left6" : "1114", "right6" : "1276", "top6" : "172", "bottom6" : "381", "class5" : "chair", "score5" : "0.3455438", "left5" : "990", "right5" : "1048", "top5" : "183", "bottom5" : "246", "class4" : "chair", "score4" : "0.34554565", "left4" : "858", "right4" : "1000", "top4" : "186", "bottom4" : "244", "class3" : "chair", "score3" : "0.87056005", "left3" : "1114", "right3" : "1276", "top3" : "172", "bottom3" : "381", "class2" : "chair", "score2" : "0.9683409", "left2" : "958", "right2" : "1151", "top2" : "203", "bottom2" : "482", "class1" : "cup", "score1" : "0.49115792", "left1" : "691", "right1" : "770", "top1" : "84", "bottom1" : "229", "class0" : "person", "score0" : "0.9980049", "left0" : "187", "right0" : "709", "top0" : "2", "bottom0" : "720", "host" : "HW13125.local.fios-router.home", "end" : "1527443620.644303", "te" : "4.380625247955322", "battery" : 100, "systemtime" : "05/27/2018 13:53:40", "cpu" : 19.7, "diskusage" : "140607.7 MB", "memory" : 65.8, "yoloid" : "20180527175341_284c6051-a45d-4757-977a-fe1dd76f295b" } I created a YOLO ID so that the JSON, the ID and the image would have that ID for keeping them in sync as we send them across various distributed networks into a cluster for storage. I also have some other metadata I thought would be helpful such as date time, run time, battery available, disk usage, cpu and memory. Those are quick and easy to grab with Python and could be useful. This is running on a Mac laptop. This could be ported to the NVIDIA Jetson TX1. It may work on the RPI3 with Movidius, but I think it may be a touch slow. Even on a Mac with no GPU and some stuff running I am getting an image every 2-3 seconds produced. It's very choppy, I would like to try this on an UBuntu workstation with a few NVidia high end GPUs and TensorFlow compiled for GPU. NiFi Flow for Ingest of JSON and Images NiFi Server to process and store data in Hive and HBase Read JSON from the Logs Directory Written by Python 3 Ingest Images from Images Directory Written by YOLO v3 TensorFlow Analysis of Captured Image You can watch the data arrive To Write Data to HBase is Easy (Just create an HBase table with a column family) Apache NiFi generates my Hive table Once we have a generate table it is populated with our data and we can query it in Apache Zeppelin (or any JDBC/ODBC Tool) Using InferAvroSchema we had a schema created, we store it in Hortonworks Schema Registry for use.
