Camera focusing based on fringe pattern matching.
A method of camera focusing based on fringe pattern matching is presented. In the method, the variance of the mismatch function is used as a focus measure. The focus measure was examined in a fringe analysis system, and the results from the three well-known focus measures-gray-level variance, image gradient, and Laplacian-were also obtained in the experiment as a comparison. The experimental re...
متن کاملPartially overlapped range images registration based on fringe pattern profilometry
Registration of two three-dimensional (3-D) point sets is a fundamental problem of 3-D shape measurement and modeling pipeline. This paper investigates the automatic pair-wise method to register partially overlapped range images generated by self-developed fringe pattern profilometry (FPP) system. The method is based on the classic iterative closest point (ICP) algorithm but combined with sever...
متن کاملSensor Pattern Noise Matching Based on Reliability Map for Source Camera Identification
Source camera identification using the residual noise pattern left by the sensor, or Sensor Pattern Noise, has received much attention by the digital image forensics community in recent years. One notable issue in this regard is that high-frequency components of an image (textures, edges) can be easily mistaken as being part of the SPN itself, due to the procedure used to extract SPN, which is ...
متن کاملA universal predictor based on pattern matching
We consider a universal predictor based on pattern matching: Given a sequence X1; : : : ; Xn drawn from a stationary mixing source, it predicts the next symbol Xn+1 based on selecting a context of Xn+1. The predictor, called the Sampled Pattern Matching (SPM), is a modi cation of the Ehrenfeucht{Mycielski pseudo random generator algorithm. It predicts the value of the most frequent symbol appea...
متن کاملSoftware Architecture Recovery based on Pattern Matching
This paper is a summary of the author’s thesis that presents a model and an environment for recovering the high level design of legacy software systems based on user defined architectural patterns and graph matching techniques. In the proposed model, a high-level view of a software system in terms of the system components and their interactions is represented as a query, using a description lan...
