Comparison of Colour Spaces for Visual Saliency

The human eye is able to locate objects or regions of importance in its field of vision. Many visual saliency models have been proposed to replicate the human visual system (HVS) in detecting salient objects in a visual scene. A colour space transformation from the RGB space is assumed to increase the detection performance, given the reason that the transformed colour space would allow a better representation of colour similar to the HVS. In this paper, comparisons are performed to validate the claim. Results from a survey performed showed that colour space transformation from the RGB space resulted in better salient detection performance.
