Edge detection is one of the most commonly used
operations in image processing and pattern recognition, the
reason for this is that edges form the outline of an object. An
edge is the boundary between an object and the background,
and indicates the boundary between overlapping objects. This
means that if the edges in an image can be identified
accurately, all of the objects can be located and basic
properties such as area, perimeter, and shape can be
measured. Since computer vision involves the identification
and classification of objects in an image, edge detection is an
essential tool. Efficient and accurate edge detection will lead to
increase the performance of subsequent image processing
techniques, including image segmentation, object-based image
coding, and image retrieval. A color image edge detection
algorithm is proposed in this paper. Average maximum color
difference value is used to predict the optimum threshold value
for a color image and thinning technique is applied to extract
proper edges. The proposed method is applied over large
database of color images both synthetic and real life images
and performance of the algorithm is evident from the results
and is comparable with other edge detection algorithms.
