Fractal Coding by Means of Local Feature Histograms
نویسندگان
چکیده
This report describes an experimental still image coder that grew out of a project in the graduate course “Advanced Video Coding” in spring 2000. The project has investigated the idea to use local orientation histograms in fractal coding. Instead of performing a correlation-like grey-level matching of image regions, the block search is made by matching feature histograms of the block contents. The feature investigated in this report is local orientation, but in principle other features could be used as well. In its current state the coder does not outperform state of the art still image coders, but the block-search strategy seems promising, and will probably prove useful in several other applications.

Local gradient pattern - A novel feature representation for facial expression recognition
Many researchers adopt Local Binary Pattern for pattern analysis. However, the long histogram created by Local Binary Pattern is not suitable for large-scale facial database. This paper presents a simple facial pattern descriptor for facial expression recognition. Local pattern is computed based on local gradient flow from one side to another side through the center pixel in a 3x3 pixels region...
متن کاملFeature selection using genetic algorithm for classification of schizophrenia using fMRI data
In this paper we propose a new method for classification of subjects into schizophrenia and control groups using functional magnetic resonance imaging (fMRI) data. In the preprocessing step, the number of fMRI time points is reduced using principal component analysis (PCA). Then, independent component analysis (ICA) is used for further data analysis. It estimates independent components (ICs) of...

In this paper we present the prototype based text matching methodology used in the Routing Sub-Task of TREC 2001 Filtering Track. The methodology examines texts on word and sentence levels. On the word level the methodology is based on word coding and transforming the codes into histograms by the means of Weibull distribution. On the sentence level the word coding is done in a similar manner as...

Recently, high-accuracy RGB-D cameras are commertially available, which are capable of providing high quality three dimension information (color and depth). In this paper, we propose an object recognition method where the techniques of object recognition in 2D are extended to 3D. Recent image classification systems mainly consist of the following three parts: feature extraction using scaleinvar...
