Multiresolution Object-of-Interest Detection of Images with Low Depth of Field

Li, J. and Wang, J. and Gray, R. and Wiederhold, G. (1999) Multiresolution Object-of-Interest Detection of Images with Low Depth of Field. In: 10th International Conference on Image Analysis and Processing (ICIAP 1999) , September 27-29, 1999, Venice, Italy.




This paper describes a novel multiresolution image segmentation algorithm for separating sharply focused objects-of-interest from other foreground or background objects in low depth of field (DOF) images, such as sports, telephoto, macro, and microscopic images. The algorithm takes a multiscale context-dependent approach to segment images based on features extracted from wavelet coeffcients in high frequency bands. The algorithm is fully automatic in that all parameters are image independent. Experiments with the algorithm on more than 100 low DOF images have shown results close to the human segmentation these images. Besides high accuracy, the algorithm also provides high speed. A 768512 pixel image can be segmented within two seconds on a Pentium Pro 300MHz PC.
