This paper proposes an efficient algorithm for edge detection. Our algorithm is based on an improved Gabor wavelets-based (IGWs) edge detector, and can detect edges with eight directions. Morphological operations can be used as techniques for images pre- or post-processing, such as morphological filtering, thinning, and pruning. In this paper, we use it to thin the edge images extracted by IGWs. Experimental...
An efficient algorithm for facial features extractions is proposed. The facial features we extracted are the edges of two eyes, nose and mouth. The algorithm is based on an improved Gabor wavelets edge detector to detect the face region and facial features regions. The experimental results show that the proposed method is robust against facial expression, illumination, and can be also effect if the...
