wai.annotations.imgaug

Inline stream processors for image augmentation:

crop: crops images
flip: flips images either left-to-right, up-to-down or both
gaussian-blur: applies gaussian blur to images
hsl-grayscale: turns RGB images into fake grayscale ones by converting them to HSL and then using the L channel for all three channels
linear-contrast: applies linear contrast to images
rotate: rotates images by a specified degree (0-360) or randomly within degree range
scale: scales images by a specified percentage (0-1) or randomly within percentage range
sub-images: extracts regions (incl annotations) from images using user-defined bounding boxes

Changelog

sub-images plugin now has a –verbose flag; only initializes the regions now once

Added sub-images plugin for extracting regions (including their annotations) based on one or more bounding box definitions from the images coming through and only forwarding these sub-images

Fixed error message of AnnotationOverlay in case data of wrong domain is coming through
Moved AnnotationOverlay into wai.annotations.imgvis module

–labels option of the add-annotation-overlay-od plugin gets respected now, also using correct label for text now (when varying the colors)

added add-annotation-overlay-od plugin to overlay the object detections on the images

added more typing hints to parameters
added ability to add augmented images rather than replace original ones, using the -m/–mode add option (–suffix overrides the default suffix)
added scale ISP for scaling images

Initial release: crop, flip, gaussian-blur, hsl-grayscale, linear-contrast, rotate
