Engineering National Institute of Technology Rourkela-769008 i Acknowledgement I would like to express my gratitude to my supervisor Prof. Samit Ari for his guidance, advice and constant support throughout my thesis work. I would like to thank him for being my advisor here at National Institute of Technology, Rourkela. Next, I want to express my respects to Prof. S.K. Patra, Prof. K. K. Mahapatra, Prof. S. Meher, Prof. S. K. Behera, Prof. Poonam Singh, Prof. A. K. Sahoo, Prof. D. P. Acharya, prof. S.K. Das and Prof. N. V. L. N. Murty for teaching me and also helping me how to learn. They have been great sources of inspiration to me and I thank them from the bottom of my heart. I would like to thank all faculty members and staff of the Department of Electronics and Communication Engineering, N.I.T. Rourkela for their generous help in various ways for the completion of this thesis. I would like to thank all my friends and especially my classmates for all the thoughtful and mind stimulating discussions we had, which prompted us to think beyond the obvious. I’ve enjoyed their companionship so much during my stay at NIT, Rourkela. I am especially indebted to my parents for their love, sacrifice, and support and would like to thank my parents for raising me in a way to believe that I can achieve anything in life with hard work and dedication .

Place: Roll No: 209EC1111 Dept of ECE, NIT, Rourkela ii ABSTARCT Hand gesture recognition system can be used for interfacing between computer and human using hand gesture. This work presents a technique for a human computer interface through hand gesture recognition that is able to recognize 25 static gestures from the American Sign Language hand alphabet. The objective of this thesis is to develop an algorithm for recognition of hand gestures with reasonable accuracy. The segmentation of gray scale image of a hand gesture is performed using Otsu thresholding algorithm. Otsu algorithm treats any segmentation problem as classification problem. Total image level is divided into two classes one is hand and other is background. The optimal threshold value is determined by computing the ratio between class variance and total class variance. A morphological filtering method is used to effectively remove background and object noise in the segmented image. Morphological method consists of dilation, erosion, opening, and closing operation. Canny edge detection technique is used to find the boundary of hand gesture in image. A contour tracking algorithm is applied to track the contour in clockwise direction. Contour of a gesture is represented by a Localized Contour Sequence (L.C.S) whose samples are the perpendicular distances between the contour pixels and the chord connecting the end-points of a window centered on the contour pixels. These extracted features are applied as input to classifier. Linear classifier discriminates the images based on dissimilarity between two images. Multi Class Support Vector Machine (MCSVM) and Least Square Support Vector Machine (LSSVM) is also implemented for the classification purpose. Experimental result shows that 94.2% recognition accuracy is achieved by using linear classifier and 98.6% recognition accuracy is achieved using Multiclass Support Vector machine classifier. Least Square Support Vector Machine (LSSVM) classifier is also used for classification purpose and shows 99.2% recognition accuracy. Download 1.15 Mb. Do'stlaringiz bilan baham: |
