public class ImageRecordReader
extends BaseImageRecordReader

Image record reader. Reads a local file system and parses images of a given height and width. All images are rescaled and converted to the given height, width, and number of channels. Also appends the label if specified (one of k encoding based on the directory structure where each subdir of the root is an indexed label)
