IMAGE COMPRESSION BY VARIABLE BLOCK TRUNCATION CODING WITH OPTIMAL THRESHOLD
收藏 引用
IEEE TRANSACTIONS ON SIGNAL PROCESSING 1991年 第1期39卷 208-212页
作者: KAMEL, M SUN, CT GUAN, L Pattern Analysis and Machine Intelligence Laboratory Department of Systems Design Engineering University of Waterloo Waterloo ONT Canada
In this correspondence we propose two modifications to the block truncation coding techniques. The first modification allows the partitioning of the image into variable size blocks rather than fixed size. The second m... 详细信息

2006 IEEE International Conference on Image Processing, ICIP 2006
作者: Sahba, Farhang Tizhoosh, Hamid R. Salama, Magdy M. A. Systems Design Engineering Pattern Analysis and Machine Intelligence Laboratory University of Waterloo Waterloo ON Canada Electrical and Computer Engineering Pattern Analysis and Machine Intelligence Laboratory University of Waterloo 200 University Ave W Waterloo ON Canada
In this paper a new approach to object extraction and recognition based on reinforcement learning is presented. We use this novel idea as a method to optimally segment the image and increase the recognition rate. The ... 详细信息

Shape-based image retrieval applied to trademark images
收藏 引用
International Journal of Image and Graphics 2002年 第3期2卷 375-393页
作者: El Badawy, Ossama Kamel, Mohamed Pattern Analysis and Machine Intelligence Laboratory Department of Systems Design Engineering University of Waterloo 200 University Avenue West WaterlooONN2L 3G1 Canada
We propose a new shape-based, query-by-example, image database retrieval method that is able to match a query image to one of the images in the database, based on a whole or partial match. The proposed method has two ... 详细信息

Automatic image registration using virtual circles
收藏 引用
International Journal of Image and Graphics 2004年 第2期4卷 281-299页
作者: Alhichri, Haikel S. Kamel, Mohamed Pattern Analysis and Machine Intelligence Laboratory Systems Design Engineering University of Waterloo 200 University Ave. West WaterlooONN2L3G1 Canada University of Waterloo Canada
The main contribution of this work is a novel set of image features called the virtual circles and their use in the registration of images under similarity transformations. A virtual circle is a circle with maximal ra... 详细信息

IEEE International Joint Conference on Neural Network
作者: Ventresca, Mario Tizhoosh, Hamid R. Pattern Analysis and Machine Intelligence (PAMI) Laboratory Systems Design Engineering Department University of Waterloo Waterloo ON N2L 3G1 Canada
The backpropagation algorithm is a very, popular approach to learning in feed-forward multi-layer perceptron networks. However, in many scenarios the time required to adequately learn the task is considerable. Many ex... 详细信息

10th Annual Genetic and Evolutionary Computation Conference, GECCO 2008
作者: Ahmadi, Abbas Karray, Fakhri Kamel, Mohamed Pattern Analysis and Machine Intelligence Lab. Department of Systems Design Engineering University of Waterloo 200 University Avenue West Waterloo ON Canada
Extracting natural groups of the unlabeled data is known as clustering. To improve the stability and robustness of the clustering outputs, clustering ensembles have emerged recently. In this paper, an ensemble of part... 详细信息
