Context:
1. In image processing, a kernel, convolution matrix, or mask is a small matrix. It is used for blurring, sharpening, embossing, edge detection, and more. This is accomplished by doing a convolution between a kernel and an image.

2. A convolution kernel, or filter, describes how each pixel will be influenced by its neighbors. For example, a blurring filter will take the weighted average of neighboring pixels so that large differences between pixel values are reduced.
