PATTERN RECOGNITION

I.

Introduction
Image pattern recognition is a representation of an important computer vision domain, consisting of classification of the patterns of a given image, based on various similarity criterions, whereas image segmentation is the subdivision an image into its constituent regions or objects, and consists of dividing the input image in a number of different objects called image segments or clusters, such that all the pixels from a segment have a common property called similarity criterion. General purpose image segmentation separates an image into homogeneous groups of connected pixels. One of the ultimate goals of image segmentation is the delineation of shapes of objects in images for purposes of object recognition and, eventually, image understanding. In generally, image segmentation algorithms are based on one of

    Bones protect our organs from potential damage. The fracture can occur in any bone of the body like wrist, ankle, hip, rib, leg, chest etc. This Paper Present the detection and segmentation of bone fracture using Fuzzy-c Means and Multilevel wavelet algorithm. Bone Fracture detection has become a research area in the medical imaging system. Bone fracture detection helps in finding the fracture in the various body parts like hand, leg, and rib fracture etc. The system is consisting of four stages to detect and segment a fracture. An efficient algorithm is proposed for bone fracture based on thresholding and fuzzy C-Means segmentation and morphological operators. Firstly remove the noise from the image and then…

    To ensure the best care of a patient while he or she goes through the various stages of cancer, it is necessary to make reliable and accurate decisions in oncological prognosis. Several prognostic markers have emerged over the recent years which can be used as indicators to mark the progression of the disease. One such marker is the mammogram image which displays the tumor present in the breast. These images are black and white in colour and many times hard to read. The main purpose of this paper is to investigate the fuzzy c-means(FCM) clustering as a fuzzy logic method to increase the acutance through segmentation of two mammogram images of the same patient via clustering.…

    Coin Detection

    In this project , we propose a coin recognition method by radius parameter detection approach. The effectiveness of the coins classification is ensured based on the parameters of the coin. Moreover, the variations in images obtained from new and old coins are also discussed. The polar coordinate image of coin on circles with different radii is used as the feature for coin recognition. Finally, the knowledge base of the coin is fed to the recognition system to classify the coin easily. For a given coin, image is scanned and stored as gray values in a matrix. The intensity of the pixel is maximized. The heuristic approach is adapted to classify the coin after pre…

    I. INTRODUCTION HE application of fuzzy techniques in image processing is a promising research field [1]. Fuzzy techniques have already been applied in several domains of image processing (e.g., filtering, interpolation [2], and morphology [3], [4]), and have numerous practical applications (e.g., in industrial and medical image processing [5], [6]). In this paper, we will focus on fuzzy techniques for image filtering. Already several fuzzy filters for noise reduction have been developed, e.g., the well-known FIRE-filter from [7]–[9], the weighted fuzzy mean filter from [10] and [11], and the…

    Histogram_thresholding

    • 3 Pages

    Theory: The histogram of an image with intensity levels in the range 0 to L-1, where L-1 is the last intensity value in an image(e.g. 255 in gray scale image) is a discrete function h(rk)=nk where rk is the kth intensity value and nk is the number of pixels in the image with intensity rk. It is common practice to normalize a histogram by dividing each of its components by the total number of pixels in the image, denoted by the product MN, where M and N are the row and column dimensions of the image. Thus a normalized histogram is given by p(rk)=nk/M*N, for k=0,1,2…,L-1. P(rk) is nothing but probability of occurrence of intensity level rk in the image. The sum of all components of a normalized histogram is equal to 1.…

    AbstractÐIn this paper, a new analytic scheme, which uses a sequence of segmentation and recognition algorithms, is proposed for offline cursive handwriting recognition problem. First, some global parameters, such as slant angle, baselines, and stroke width and height are estimated. Second, a segmentation method finds character segmentation paths by combining gray scale and binary information. Third, Hidden Markov Model (HMM) is employed for shape recognition to label and rank the character candidates. For this purpose, a string of codes is extracted from each segment to represent the character candidates. The estimation of feature space parameters is embedded in HMM training stage together with the estimation of the HMM model parameters. Finally, the lexicon information and HMM ranks are combined in a graph optimization problem for word-level recognition. This method corrects most of the errors produced by segmentation and HMM ranking stages by maximizing an information measure in an efficient graph search algorithm. The experiments in dicate higher recognition rates compared to the available methods reported in the literature.
