Abstract:
1. A fast high precision matching method comprising the steps of: a) Input an image; b) Input a template; c) Perform initial search using the input image and the template based on a matching function to create an initial search result output containing only matching function values at discrete (x,y) positions; d) Create high precision matching function by interpolating the matching function values of discrete (x,y) positions making them matching function values of subpixel positions or of invariant high precision parameters; e) Perform high precision match by high precision matching function maximization directly using the matching function values at discrete (x,y) positions from the step (c), the input image, and the same template from step (b) to create a high precision match result output without image matching wherein the high precision match result output around a pixel position (x,y) is the subpixel values α and β and other parameters correspond to the maximum value of the high precision matching function.
