As an example of algorithm: Iteratively delete (or erode) pixels inside the object (letter) to shrink it without shortening it or breaking it apart. Note that this is an iterative process. In general, you may stop the iteration after several times. Iterate it 3-5 times gives good and fast result.
WebThin the binary image in Mat . Here, the image is assumed to be 2D or 3D; if 3D, then the z information is found along the channels dimension. The thinning is performed in-place. The image is converted to uint8 if required; non-zero pixels are considered foreground and zero pixels background. WebOriginal image.
