|
* @brief Extracts FAST10 corners and scores from the image based on the mask.
|
|
* The mask specifies pixels to be ignored by the detector
|
|
* designed for corner detection on Qualcomm's processors, provides enhanced speed.
|
|
*
|
|
* @param src 8-bit grayscale image
|
|
* @param mask Optional mask indicating which pixels should be omited from corner dection.
|
|
Its size should be k times image width and height, where k = 1/2, 1/4 , 1/8 , 1, 2, 4 and 8
|
|
For more details see documentation to `fcvCornerFast9InMaskScoreu8` function in FastCV
|
|
* @param coords Output array of CV_32S containing interleave x, y positions of detected corners
|
|
* @param scores Optional output array containing the scores of the detected corners.
|
|
The score is the highest threshold that can still validate the detected corner.
|
|
A higher score value indicates a stronger corner feature.
|
|
For example, a corner of score 108 is stronger than a corner of score 50
|
|
* @param barrier FAST threshold. The threshold is used to compare difference between intensity value
|
|
of the central pixel and pixels on a circle surrounding this pixel
|
|
* @param border Number for pixels to ignore from top,bottom,right,left of the image. Defaults to 4 if it's below 4
|
|
* @param nmsEnabled Enable non-maximum suppresion to prune weak key points
