Moving Object detection is a challenging tool because shape and size of the object in a video vary significantly according to camera direction, partial occlusion and poses. Significant research has been carried out for detecting people in videos. Traditional methods for detecting human used sliding window approach which involved scanning various sizes of windows across an image. Hence in this work...
This paper deals with the problem of textured image segmentation. Our approach employs a recently developed method, the so called Wavelet Scattering Transform, for the process of feature extraction to get robust and invariant system to small deformations. The classification of scattering energy distribution is done by support vector machine classifier(SVM). To obtain a more accurate result of segmentation,...
This paper proposes a method for segmentation of images containing both textual and graphical data. The method uses wavelet transformation to build the feature vector and a pattern recognition technique to classify areas of a document image. Values of wavelet coefficients distribution histogram of the source images sliding window serve as elements of a feature vector. For recognition of document area...
In this paper, a novel method for brain SPECT image feature extraction based on the Empirical Wavelet Transform (EWT) have been proposed. The method is applied to assist the diagnosis of Brain Tumor by the detecting the tumor present in the abnormal brain image. EWT is used to decompose the image into a number of subband images and Fuzzy C-means (FCM) clustering algorithm is used as an image segmentation...
Labor induction is defined as the artificial onset of labor for the purpose of vaginal birth. Cesarean section is one of the potential risk of labor induction as it occur in about 20% of the inductions. A ripe cervix (soft and distensible) is needed for a successful labor. During the ripening cervical tissues experience micro structural changes: collagen becomes disorganized and water content increases...
There are many kinds of corporeal ingredients in urinary sediment which must be identified to confirm the diagnosis of an abnormality. In this paper, we refine a method which integrates both Gabor filter and scattering transform for texture analysis in urinary sediment images. The proposed scheme is based on the conventional Gabor filter and the recently developed scattering transform. The Gabor filter...
This paper describes the application of image processing techniques for identification of leather defects using wavelet feature extraction method. Defects occur in leather and are identified at different stages of processing such as pre tanning, post tanning, crust, finishing etc., Manual defect inspection and analysis varies from person to person and is labor intensive, tedious, misjudgment occurs...
Synthetic Aperture Radars are powerful observation tools in cases where the utilization of optical data is restricted. As one of the main applications of these systems is the control of maritime traffic, a land mask needs to be estimated. In this paper two different processing schemes are proposed in order to perform the land mask estimation on a TerraSAR-X acquired SAR image. The first one consists...
In this paper, an efficient algorithm for texture recognition of synthetic aperture radar (SAR) images is developed based on wavelet transform as a feature extraction tool and support vector machine (SVM) as a classifier. SAR image segmentation is an important step in texture recognition of SAR images. SAR images cannot be segmented successfully by using traditional methods because of the existence...
The retina is an important field in the medical treatment of pathologies. Segmentation of the vasculature in retinal fundus images plays an important role in the diagnosis of many eye diseases such as hypertension, arteriosclerosis and blindness caused by diabetes. Comparison of kernel classifiers for the vessel segmentation is presented in this work. Kernel based classifier such as Support Vector...
Among gestures in non-verbal communication, pointing gesture can be taken as one of natural human computer interfaces. Vision based hand pointing is an optimal model for human-computer interaction (HCI). One of key problems among the vision based pointing gesture is how to recognize the pointing. Aiming at some limits existing in the literature, a novel method is developed to estimate pointing gestures...

We present two of spatial information which are Principal Component Analysis (PCA) image using 2-D discrete wavelet transform (DWT), and image segmentation. The DWT is used to generate spatial...
In this paper, a three-step classification method is proposed for remote sensing images with the spectral and texture features based on the Support Vector Machine (SVM) classifier. The image is first segmented into regions with the spectral features. Then, texture features are extracted from each region by the undecimated wavelet transform. Third, the SVM is used to classify the image with these extracted...
Glaucoma is the second leading cause of blindness worldwide. The risk of glaucoma can be determined by calculating the cup to disc ratio in retinal fundus images. To accurately detect the optic cup, kinks or bends in small and medium vessels are important indicators of the cup boundary. In this paper, we present a method of detecting such vessels, through the extraction of patches and generation of...
Image segmentation is a key step in the application of Synthetic Aperture Radar (SAR) images, but because of the existing of speckles in SAR images, image can not be divided well by using traditional methods. According to the remarkable result of wavelet transform on texture feature extraction, image filtration and the advantages of support vector machine (SVM) classification, an efficient method...
In this paper, we introduce a method of functionally classifying lung cancer cells from normal cells by using Tetrakis Carboxy Phenyl Porphine (TCPP) and well-known computational intelligent techniques. Tetrakis Carboxy Phenyl Porphine (TCPP) is a porphyrin that is able to label cancer cells due to the increased numbers of low density lipoproteins coating the surface of cancer cells and the porous...
