A Pca-wavelet Based Compression for Distance Learning Images
نویسندگان
چکیده
The large volume of images used in Distance Learning System are required to be compressed in a good ratio to release the storage loading of computer servers. A new image coding Scheme based on Principle Components Analysis (PCA) and Wavelet decomposition is proposed in this paper. Our algorithm includes 1) Principle Components Analysis (PCA)to reduce the information redundancies along temporal dimension; 2) a texture energy (TE) based technique used to optimize the PCA analysis; 3) Wavelet decomposition and optimized LBG algorithm for compression along spatial dimention. The experimental results demonstrate that our proposed coding scheme achieves good performance. Key–Words: Distance Learning, Image Compression, PCA, Wavelet Decomposition, Image Classification

PCA-Pyramids for Image Compression
This paper presents a new method for image compression by neural networks. First, we show that we can use neural networks in a pyramidal framework, yielding the so-called PCA pyramids. Then we present an image compression method based on the PCA pyramid, which is similar to the Laplace pyramid and wavelet transform. Some experimental results with real images are reported. Finally, we present a ...
متن کاملPlanelet Transform: A New Geometrical Wavelet for Compression of Kinect-like Depth Images
With the advent of cheap indoor RGB-D sensors, proper representation of piecewise planar depth images is crucial toward an effective compression method. Although there exist geometrical wavelets for optimal representation of piecewise constant and piecewise linear images (i.e. wedgelets and platelets), an adaptation to piecewise linear fractional functions which correspond to depth variation ov...
متن کاملWavelet–PCA–Based Compression Method for Color Images
From the birth of multi–spectral imaging techniques, there has been a tendency to consider and process this new type of data as a set of parallel gray–scale images, (instead of an ensemble of an n–D realization). Although, even now, some researchers make the same assumption, it is proved that using vector geometries leads to more realistic results. In this paper, using a proposed PCA–based eige...
متن کاملAn Efficient Feature Extraction Method for Iris Recognition Based on Wavelet Transformation
One of the most reliable biometric is the iris, due to its stability, uniqueness and noninvasive nature. One of the difficult problems in feature based iris recognition is the speed of matching, which is significantly influenced by time required for feature extraction process, size of the template database stored, ...etc. In this paper, a new approach of iris image compression and feature extra...
متن کاملAssessment of the Wavelet Transform for Noise Reduction in Simulated PET Images
Introduction: An efficient method of tomographic imaging in nuclear medicine is positron emission tomography (PET). Compared to SPECT, PET has the advantages of higher levels of sensitivity, spatial resolution and more accurate quantification. However, high noise levels in the image limit its diagnostic utility. Noise removal in nuclear medicine is traditionally based on Fourier decomposition o...
