Texture resynthesis using principle component analysis

چکیده
We present a method for analyzing and resynthesizing inhomogeneously textured regions in images for the purpose of advanced compression. We first define image blocks in a way that they cover regions with homogenious texture. These blocks are transformed each in turn. For the transform we use the so called Principle Component Analysis. After the transform into the new domain we statistically analyze the resulting coefficients. For resynthesizing new texture we generate random numbers that exactly meet these statistics. Using the inverse transform the random coefficients are finally transformed back into the spatial domain. The visual appearance of the resulting artificial texture matches the original to a very high degree.

Improving the quality of images synthesized by discrete cosines transform – regression based method using principle component analysis
Purpose: Different views of an individuals’ image may be required for proper face recognition. Recently, discrete cosines transform (DCT) based method has been used to synthesize virtual views of an image using only one frontal image. In this work the performance of two different algorithms was examined to produce virtual views of one frontal image. Materials and Methods: Two new meth...
متن کاملPrediction of mental disorders after Mild Traumatic Brain Injury: principle component Approach
Introduction: In Processes Modeling, when there is relatively a high correlation between covariates, multicollinearity is created, and it leads to reduction in model's efficiency. In this study, by using principle component analysis, modification of the effect of multicolinearity in Artificial Neural Network (ANN) and Logistic Regression (LR) has been studied. Also, the effect of multicolineari...
متن کاملTexture Analysis using the Multiresolution Fourier Transform
A new frequency domain approach to the analysis of texture is described. The method works by identifying, for pairs of texture `patches' of a given size, the a ne co-ordinate transformation which gives the best match between them. This allows the analysis to take account of the geometric warping which is typically found in images of natural textures. The scheme is implemented e ciently in the F...
