Detailed Description

Edge detection on input image.

Perform an edge detection with specified algorithm.

Example (Sobel):

Procedural::TextureBuffer bufferCell(256);
Procedural::Cell(&bufferCell).setDensity(4).setRegularity(234).process();
Procedural::EdgeDetection(&bufferCell).setType(Procedural::EdgeDetection::DETECTION_SOBEL).process();
