Utils for processing video dataset features.
Functions
crop_image(...): Crops the image sequence of images.
decode_image(...): Decodes PNG or JPEG raw bytes string into a RGB uint8 Tensor.
decode_jpeg(...): Decodes JPEG raw bytes string into a RGB uint8 Tensor.
normalize_image(...): Normalizes images.
random_crop_resize(...): First crops clip with jittering and then resizes to (output_h, output_w).
random_flip_left_right(...): Flips all the frames with a probability of 50%.
resize_smallest(...): Resizes frames so that min(height, width) is equal to min_resize.
sample_linspace_sequence(...): Samples num_windows segments from sequence with linearly spaced offsets.
sample_segment_sequence(...): Samples a single segment of size num_frames from a given sequence.
sample_sequence(...): Samples a single segment of size num_steps from a given sequence.
