What is shift invariant in image processing?

Shift Invariance simply refers to the 'invariance' that a CNN has to recognising images. It allows the CNN to detect features/objects even if it does not look exactly like the images in it's training period. Shift invariance covers 'small' differences, such as movements shifts of a couple of pixels.

What is meant by shift invariant?

A shift-invariant system is one where a shift in the independent variable of the input signal causes a corresponding shift in the output signal. So if the response of a system to an input is , then the response to an input is .

What is a shift invariant system and example?

Shift-invariance: this means that if we shift the input in time (or shift the entries in a vector) then the output is shifted by the same amount. Mathematically, we can say that if f(x(t)) = y(t), shift invariance means that f(x(t + ⌧)) = y(t + ⌧).
