A nature-inspired method of image feature extraction is proposed based on the ant swarm system. The perceptual graph is proposed to represent the relationship between adjacent image points, from which the image features can be extracted. The ant colony system is applied to build the perceptual graph. Edge feature extraction and image segmentation are implemented with the proposed method. The experimental...
The scale-rate is presented as a novel feature of local complexity in digital images. The scale-rate is experimentally proved to be an important feature of image edge areas. Multi-feature edge extraction is achieved with the scale-rate and image intensity discontinuity. Experimental results show that exploiting the scale-rate feature improves the performance of edge extraction.
