详 情 说 明

The purpose of this function is to detect circular shapes within a grayscale image and determine their center positions and radii. To achieve this, the CircularHough_Grd function is utilized. This function is a variation of the Circular Hough transform that is based on the gradient field of the image. It is important to note that this function only operates on grayscale images and not black and white bitmaps.

The implementation of the Circular Hough transform in this function does not contain any loops, resulting in faster operation, but also greater memory consumption. In terms of input, the function requires a 2-D grayscale image (not a black and white bitmap), as well as several additional parameters such as radrange, grdthres, fltr4LM_R, multirad, and fltr4accum.

Overall, this function is a useful tool for detecting circular shapes within grayscale images and can provide valuable information about their center positions and radii.
