WebHomogeneous Blur is the most simplest method of smoothing an image. It is also called as Homogeneous Smoothing, Homogeneous Filtering and Box Blurring. In this technique, each pixel value is calculated as the average value of the neighborhood of the pixel defined by the kernel. Kernels used in the homogeneous blur is called normalized box filter. WebBox filter. We are going to implement an algorithm, which applies a box filter of size r to a gray scale image. The box filter simply calculates the mean value of the surrounding floats, illustrated as follows, and the image itself is represented as a std::vector and an integer representing its width. Note that we simplify the algorithm ...

Image Filtering — OpenCV 2.3.2 documentation

WebThe box filter simply calculates the mean value of the surrounding floats, illustrated as follows, and the image itself is represented as a std::vector and an integer representing its width. Note that we simplify the algorithm by avoiding the borders, which relieves us from out-of-bounds checks: Box filter of an individual grid element WebThe process of performing convolution with kernel having anchor point of a particular shape in a given input image is called dilate () function in OpenCV. The dilate () function starts with computing the minimum pixel value by overlapping the kernel over the input image. And then the image is replaced by the kernel anchor at the center.
