Amit Baghel updated SPARK-25157:
--------------------------------
Description: We are doing video analytics for video streams using Spark. At
present there is no direct way to stream video frames or image files to Spark
and process using Structured Streaming and Dataset. We are using Kafka to
stream images and then doing processing at spark. We need a method in Spark to
stream images from directory. Currently *{{DataStreamReader}}* doesn't support
Images. With the introduction of *org.apache.spark.ml.image.ImageSchema* class,
we think streaming capabilities can be added for images. It is fine if it won't
support some of the structured streaming features as it is a binary file.
Schema used in ImageSchema class for image can be used in Dataset. This method
could be similar to *mmlspark* *streamImages* method.
