: Specialized filters can detect sharp changes in intensity, effectively "outlining" shapes within data.
: The final sequence of these output values forms a feature map , which represents the detected presence and strength of the target pattern across the entire input. Practical Applications S W A T 1x3
A 1x3 filter generates a "feature" by performing a —a mathematical operation where the filter slides across an input array to identify specific patterns like edges, gradients, or intensities. : Specialized filters can detect sharp changes in
: The filter is placed over the first three elements of the input space. Each value in the filter is multiplied by the corresponding input value, and the results are summed to create a single output pixel . Example : If the input is [2, 4, 6] , the result is : The filter is placed over the first
: You define a filter with specific weights, such as [2, -1, 0.1] .
