# CVUtils (Computer Vision Utils)

Python video and image manipulation utilities mainly using opencv

## Main Scripts

File with pattern `main_xxxx` were executable scripts for scripting usage

### main_dlib_train_object_detector.py

Used as sample to train object detector. 

refer to https://github.com/davisking/dlib/blob/v19.24.4/python_examples/train_object_detector.py

### main_image_analysis.py

Used to perform image analysis on the input image

### main_image_contours.py

Used to find image contours on the input image

### main_image_feature_matching.py

Used to match image feature

### main_image_histogram_color.py

Used to show input image histogram on color

### main_image_histogram_gray.py

Used to show input image histogram on gray color

### main_image_threshold.py

Used to show input image threshold

### main_pascalvoc_mediapipe_rename.py

Used to rename image in Pascal VOC dataset.

PASCAL VOC based on mediapipe dataset structure where dataset directory consist of `images` and `Annotations` see:

https://developers.google.com/mediapipe/api/solutions/python/mediapipe_model_maker/object_detector/Dataset

 

### main_video2image.py

Used to split video to images.

Use `--filter-path` to point to your custom filter for each frame.

Example run python with: `main_video2image.py assets/video/test.avi output/video2image --filter-path main_video2image/filter/colormap_autumn.py`

See example on how to write [**filter function**](https://github.com/rh-id/python-CVUtils/blob/master/main_video2image/filter/colormap_autumn.py)

### main_video2image_youtube.py

Used to split video to images from youtube links.

`links_path` point to text file that contains youtube link per line see [**example**](https://github.com/rh-id/python-CVUtils/blob/master/assets/text/youtube.txt) 

Use `--filter-path` to point to your custom filter for each frame.

Example run python with: `main_video2image.py assets/video/test.avi output/video2image --filter-path main_video2image/filter/colormap_autumn.py`

See example on how to write [**filter function**](https://github.com/rh-id/python-CVUtils/blob/master/main_video2image/filter/colormap_autumn.py)

### main_video_info.py

Used to show video attributes/information

### main_video_info_scan.py

Used to scan directory and export video attributes/information
