"WebLinear filtering is one of the most powerful image enhancement methods. It is a process in which part of the signal frequency spectrum is modified by the transfer function of the filter. In general, the filters under consideration are linear and shift-invariant, and thus, the output images are characterized by the convolution sum between the input image and the filter … " - Box filter linear

WebLinear shift-invariant image filtering • Replace each pixel by a linearcombination of its neighbors (and possibly itself). • The combination is determined by the filter’s kernel. • The same kernel is shiftedto all pixel locations so that all pixels use the same linear combination of their neighbors. A box blur (also known as a box linear filter) is a spatial domain linear filter in which each pixel in the resulting image has a value equal to the average value of its neighboring pixels in the input image. It is a form of low-pass ("blurring") filter.

Filtering Methods in OpenCV 1. Filter2d in OpenCV. The cv2.filter2D function provided by the OpenCV library convolves an image with a kernel. An arbitrary linear filter is applied to the image using this function.

WebLinear filters such as the box and the Gaussian filters tend to create more blurring of image details than do most non-linear filters. An increase in their ability to smooth noise corresponds to an increase in the blurring effect. Many non-linear filters fall into the category of order statistic neighbour operators.
