Correlation and Convolution Class Notes for CMSC , Fall David Jacobs Introduction Correlation and Convolution are basic operations that we will perform to extract information from images. They are in some sense the simplest operations that we can perform on an image, but they are extremely useful. Moreover, because they are simple, they can be analyzed and understood very well, .

Each chapter covers the. In digital image correlation (DIC), to obtain the displacements of each point of interest, a correlation criterion must be predefined to evaluate the similarity between the reference subset and the target sub- set. The correlation criterion is of fundamental importance in DIC, and various correlation criteria have been designed and used in literature. However, little research has been carried.

Introduction Digital image correlation (DIC), which was originally proposed by Peters et al. [1] and Yamaguchi [2] at the beginning of the s, is a non-interference and non-contact full-ield optical measurement technology. With the rapid development of digital camera and computer software and hardware in recent years, digital image correlation method has been increasingly widely used [3. Recent advances have enabled the use of digital image correlation (DIC) to calculate the surface displacements of chosen targets in a series of digital images with a high degree of accuracy. Images are recorded during an experiment and are afterwards post-processed to find relevant information including, but not limited to, a) global displacement, b) relative displacement and c) changes in.
