Scale invariant template matching
WebSep 1, 2014 · The template matching process involves cross-correlating a template image with a target image using a sliding-window method based on various similarity measures. As basic similarity measures, the sum of squared or absolute differences (SSD/SAD) and NCC have been widely used.

WebWalk around the perimeter and find a profile of distances of the edges around the center of the template. This is the radial profile of the template. Divide by largest distance, to be … WebDue to the occurrence of defect in the wafer, the template and the sample wafer-level microscopic image might be different. Among existing template matching methods, key point feature matching methods match image position by local feature of multiple locations. Key point feature matching method define specific local structure as keypoint.
WebTo compare and match objects in images, template matching is a widely adopted technique. Nevertheless, template matching cannot deal with occlusion or scaling very well. It is also very sensitive to changes in ... Lowe, D. G. , “Distinctive image features from scale-invariant keypoints,” in International Journal of Computer Vision, 2004. [7 ... WebOnly a single candidate then undergoes Zernike-moment template matching using rotation-invariant properties [14,17]. Radial projection has also been shown to be applicable to template matching . Radial projection transforms a 2D gray-level image into 1D space and the scale invariance is constructed in the form of radial lines.
