Image Processing 101: Spatial Filters (Convolution)

In the last post, we discussed gamma transformation, histogram equalization, and other image enhancement techniques. The commonality of these methods is that the transformation is directly related to the pixel gray value, independent of the neighborhood in which the pixel is located. In this post, we take a look at the spatial domain enhancement where…
