Webmask determines the type of operation done to the signal. 7.2.1 Noise Reduction Noise reduction is accomplished by averaging, which corresponds to low pass (or low emphasis) filtering. This can be accomplished by convolving the image with a spatial mask that has all positive coefficients. Some common common low pass filters are 1 9 2 4 1 1 1 ...

WebJan 20, 2024 · The key point of masks is that they allow us to focus our computation only on regions of the image that interest us. Focusing our computations on regions that interest us dramatically impacts when we explore topics such as machine learning, image classification, and object detection. WebSpatial domain operations can be further broken down into point-processing and mask-processing operations. Both produce a new version of the original image; the difference lies in which pixel/voxel intensities are used to determine the new intensity at any given point.
