Here’s some interesting link I found from ‘ IMAGE AND VISUAL REPRESENTATION GROUP IVRG ‘
1. The free book of ‘joy of visual perception‘

Their algorithm: Radhakrishna Achanta and Sabine Susstrunk, Saliency Detection using Maximum Symmetric Surround, International Conference on Image Processing (ICIP), Hong Kong, September 2010.
is dealing with the problem of “salient regions comprise more than half the pixels of the image, or if the background is complex, the background gets highlighted instead of the salient object. “. Tested on several images, though not working for all cases, but it’s quite a nice saliency detection since it dose avoid some problems by most of the saliency detection — focusing mostly on high frequency, dense edge region.
Also, it seem that a website is built based on their research for automatically cropping image to give the best composition.
