   Transform byte array(original image file in byte) to OpenCVMat

2. class ChainedFeatureTransformer extends FeatureTransformer

   

   A transformer chain two FeatureTransformer together.

3. class DistributedImageFrame extends ImageFrame

   

   Distributerd ImageFrame, it keeps an rdd of ImageFeature

4. abstract class FeatureTransformer extends Transformer[ImageFeature, ImageFeature]

   

   FeatureTransformer is a transformer that transform ImageFeature

5. class ImageFeature extends Serializable

   

   Each ImageFeature keeps information about single image, it can include various status of an image, e.g.

   Each ImageFeature keeps information about single image, it can include various status of an image, e.g. original bytes read from image file, an opencv mat, pixels in float array, image label, meta data and so on. it uses HashMap to store all these data, the key is string that identify the corresponding value
