Canny aperture size
WebHere, we present an image processing method using Gaussian smoothing filter and threshold segmentation, followed by differentiation and Canny image edge detection for tracking changes in glottis dimensions (the opening area). A quantitative assessment of true glottic size was also developed for calibration in our study. WebCanny Edge detection.

WebOpenCV puts all the above in single function, cv2.Canny(). Syntax of the function is: edges = cv2.Canny(img,100,200, aperture_size =3, L2gradient = True ) First argument is our input image; Second and third arguments are our minVal and maxVal respectively; Third argument is aperture_size. It is the size of Sobel kernel used for find image ... WebAug 24, 2013 · Setting Canny()'s apertureSize parameter larger is somewhat like working with a smaller image, because a larger aperture is doing more blurring/smoothing of the details of the image. Setting HoughLinesP() 's rho and theta parameters larger is somewhat like working with a smaller image because you are lumping together small differences in …
