Albumentation is a tool that can customize [elastic, grid, motion blur, shift, scale, rotate, transpose, contrast, brightness, etc] to the images/pictures before you slot those into the model. You may also want to check out all available functions/classes of the module albumentations, or try the search . Official Albumentation website describes itself as. Example 01: Rotate a Line Segment 90 Degrees Clockwise. This change was necessary to prevent simultaneous install of both opencv-python-headless and opencv-python (you can read more about the problem in this issue).If you still need imgaug as a dependency, you can use the pip install -U albumentations[imgaug] command to install Albumentations with . Completely or partially transform the input image to its superpixel representation.
