Methods

BlurRegion(Mat, Rect)

Applies a Gaussian blur to a specific region within a video frame.

public static void BlurRegion(Mat img, Rect region)

Parameters

img Mat

The video frame (Mat) to process.

region Rect

The rectangular region of interest to blur.

PixelateRegion(Mat, Rect, int)

Pixelates a specific region within a video frame.

public static void PixelateRegion(Mat frame, Rect region, int pixelSize)

Parameters

frame Mat

The video frame (Mat) to process.

region Rect

The rectangular region of interest to pixelate.

pixelSize int

The size of the "pixel" blocks. Larger values result in more abstract pixelation.

Remarks

This method works by downscaling the region of interest and then upscaling it back to the original size using nearest-neighbor interpolation, creating a blocky effect.

ProcessCache(Mat, ref List<Tuple<CVFace, int>>, bool, bool)

Processes the list of cached faces, updates their state, merges overlapping areas, and applies visual effects (blur/pixelate).

public static void ProcessCache(Mat frame, ref List<Tuple<CVFace, int>> facesCacheList, bool blur, bool pixelate)

Parameters

frame Mat

The current video frame to draw on or modify.

facesCacheList List<Tuple<CVFace, int>>

The list of cached faces and their remaining lifetimes.

blur bool

if set to true, applies a blur effect to the cached face regions.

pixelate bool

if set to true, applies a pixelation effect to the cached face regions.
