Using Python and OpenCV to detect the border of a light image on a gray background, crops and corrects its geometry.
## help
```
ai_crop_images [-h] [-V] (--images IMAGES | --image IMAGE) [--output OUTPUT] [--repair REPAIR] [--gamma GAMMA] [--morph MORPH] [--blur {3,5,7,9,11,13}]
[--normalize NORMALIZE] [--dilate] [--ratio RATIO] [--min_height MIN_HEIGHT] [--detection_height DETECTION_HEIGHT] [--no_iteration]
[--debug] [--log] [--noskip] [--all_input]
options:
-h, --help show this help message and exit
-V, --version show version of app
--images IMAGES Directory of images to be scanned
--image IMAGE Path to single image to be scanned
--output OUTPUT Directory to output result images, default: 'output'
--repair REPAIR If the output folder is not empty, then save to the recovery folder, by default: None
--gamma GAMMA Gamma image correction pre-filter, default: '4.0', 1 - Off
--morph MORPH morph image correction for smooth contours, default: '35'. 0 - Off
--blur {3,5,7,9,11,13}
image blur kernel size, default: '5'
--normalize NORMALIZE
normalize_scale image correction pre-filter, default: '1'. 1 - Off, 1.2 - for start
--dilate dilate, CV operation to close open contours with an eclipse. default: 'off'
--ratio RATIO desired correction of the image aspect ratio H to W, default: '1.294'
--min_height MIN_HEIGHT
desired minimum height of the output image in px, default: '1000'
--detection_height DETECTION_HEIGHT
internally downscale the original image to this height in px for the found border, default: '900'
--no_iteration disable the iteration process to automatically adjust the gamma and dilate values in case of an unsuccessful result, default:
iteration is enabled.
--debug debug, CV operation for single image only
--log store a list of skipped images and images with comments in log files
--noskip no skip wrong images, like output same size, or result less than 800x1000. Copy original if problem. Default: skipped
--all_input Scan all images in the input folder without skipping the search for already processed images in the output folder
```
