Image Enhancement For spatial domain filtering, we are performing filtering operations directly on the the pixels of an image. Spatial Filtering is sometimes also known as neighborhood processing. Neighborhood processing is an appropriate name because you define a center point and perform an operation (or apply a filter) to only those pixels in predetermined neighborhood of that center point. Linear spatial filtering is a versatile method for image filtering and can achieve many effects, such as blurring, sharpening, embossing, outlining, etc.

Corner pixels are extended in 90° wedges. Other edge pixels are extended in lines. Wrap Correlation and Convolution Linear spatial filtering can be described in terms of correlation and convolution Correlation: The process of moving a filter mask over a signal (the image in our case) and computing the sum of products at each location Convolution: Similar to correlation but the filter mask is first rotated by 180° The purpose of this practical is for you to build on practical 1 and learn about the process of spatial (convolution) filtering. Note that convolution is a mathematical operation involving the modification of one function by another to produce a third (output) function.

The filtering operation based on the x-y space neighborhood is called spatial domain filtering. The filtering process is to move the filter point-by-point in the image function f (x, y) so that the center of the filter coincides with the point (x, y). The experimental setup of Spatial Filtering is depicted in Fig.1 Spatial Filtering with Pinholes consists of a converging lens having a short focal length, a metallic foil which has a small Linear Spatial Filtering (Convolution) The process consists of moving the filter mask from pixel to pixel in an image. At each pixel (x,y), the response is given by a sum of products of the filter coefficients and the corresponding image pixels in the area spanned by the filter mask. Convolution is a common algorithm in linear algebra, machine learning, statistics, and many other domains.

The unsharp filter is implemented as a window-based operator, i.e. it relies on a convolution kernel to perform spatial filtering. It can be implemented using an appropriately defined lowpass filter to produce the smoothed version of an image, which is then pixel subtracted from the original image in order to produce a description of image edges, i.e. a highpassed image.

Convolution is a common algorithm in linear algebra, machine learning, statistics, and many other domains. The tutorials in this section will demonstrate how to use the building blocks that Spatial provides to do convolutions. Spatial frequencies Convolution filtering is used to modify the spatial frequency characteristics of an image. What is convolution? Convolution is a general purpose filter effect for images.
