Opencv median blur
WebIn order to remove random variations in the pixel values of the given image or the noise, we make use of the median filter in OpenCV. The function medialBlur () is used to remove the noise from the given image. The image whose noise must be removed is read using imread () function. Then medianBlur () function is applied on the image along with ... Web20 de jun. de 2013 · The OpenCV documentation seems to be very clear: src – input 1-, 3-, or 4-channel image; when ksize is 3 or 5, the image depth should be CV_8U, CV_16U, or CV_32F, for larger aperture sizes, it can only be CV_8U. As you need to cater for signed values, I think your best option is to use CV_32F. Also, the documentation says.

Did you know?
WebOpenCV Median Blur. The median blur operation is quite similar to the Gaussian blur. OpenCV provides the medianblur() function to perform the blur operation. It takes the median of all the pixels under the kernel area, and the central element is replaced with this median value. It is extremely effective for the salt-and-paper noise in the image.

Viewed 5k times WebPixels that are black contribute 0 to the average. Thus, to adjust the average to only include non-black pixels, you need to adjust the size you used for smoothing. This adjusted size (actually the scale) is obtained by blurred_mask = cv2.blur (mask). E.g. if you have a 3-by-3 kernel for smoothing and 4 pixels are black, the value at the kernel ...
