information obtained during UC is not discarded‚ but is used as an initial step toward subsequent SC. Thus‚ the power of both image analysis strategies can be combined in an integrative computational procedure. This is achieved by applying “Hyper-BF network”. Here we worked a different procedures for the training‚ preprocessing and vector quantization in the application to medical image segmentation and also present the segmentation results for multispectral 3D MRI data sets of the human brain with respect

information or arrangement of the structure found in an image‚ is an important feature of many image types. In a general sense‚ texture refers to surface characteristics and appearance of an object given by the size‚ shape‚ density‚ arrangement‚ proportion of its elementary parts. Due to the signification of texture information‚ texture feature extraction is a key function in various image processing applications‚ remote sensing and contentbased image retrieval. Texture features can be extracted in several

The perception of color is essential to our visual experience. Since 1880s visual artists and storytellers have used moving images to create amazing works. Movies have inspired as‚ Thrilled as and captured our imagination. Film helped share our experiences and dreams. Photo-chemical film has been exclusive format used to capture‚ develop‚ project and store moving images for more than 100 years. And it is only recently that the new technology has emerged that is challenging films place is the gold

producers. And there is no foreseeable likelihood that they would be capable to imitate this feature even within a pretty long time. The recognition system is composed of three parts. The captured image is first preprocessed by reducing data dimensionalities and extracting its features by using image processing toolbox in MATLAB. According to the HSV (Hue‚ Saturation‚ Value) color space‚ the work of color feature extraction is finished. The second one is recognition in which the core is neural network

spatial information. In addition to image information‚ the classification and identification information is provided in Hyperspectral imaging systems[4]. It is useful for various industrial and other applications‚ which are in research level[20]. The need for Hyperspectral Imaging is on increasing level owing to accessibility and availability of the immediate treatment for the snail fever[43]. It is cost effective with high performance

In Digital image processing‚ the given image is broken down into many pixels and a numerical value is attributed to each of the pixel resulting in an array of numbers. These numbers are analyzed to get the required information from the image. It is used in Optical character recognition‚ Medical imaging analysis‚ Digital photoelasticity‚ Digital image correlation and real time sports analysis. Pre-processing an image refers to applying filters to the image to get a better image in terms of contrast

subspace. The projection operation requires many floating-point multiplications and additions‚ which makes the projection process computationally expensive. To tackle this problem‚ this project proposes two simple-but-effective fast subspace learning and image projection methods‚ fast Haar transform (FHT) based principal component analysis. The advantages of this methods result from employing both the FHT for subspace learning and the integral vector for feature extraction. Experimental results on face‚iris
