getContour(grayscaledTexture, textureShape, threshold, winSize, maxNearCount, outTensor): number
Looks for contour points in a grayscale texture, or any one-channel tensor.
grayscaledTexture - Float32Array of size (width * height). Grayscale texture or one-channel tensor to evaluate
textureShape - Should be {width, height, 1}
threshold - Quality value threshold for found contour points
Each contour point found must satisfy these conditions:
The point's quality value should be >= threshold
The number of points which have values < threshold and lie in the rectangle with left corner vec2(x-winSize, y-winSize) and right corner vec2(x+winSize-1, y+winSize-1) should be <= maxNearCount
outTensor - Float32Array where results are written. Found contour points are written in the format: x0, y0, x1, y1, etc.
The number of points found will not exceed outTensor's size / 2.
