Illumination and Expression Invariant Recognition Using SSIM Based Sparse Representation

Khwaja, Asim; Asthana, Akshay; Goecke, Roland


The sparse representation technique has provided a new way of looking at object recognition. As we demonstrate in this paper, however, the mean-squared error (MSE) measure, which is at the heart of this technique, is not a very robust measure when it comes to comparing facial images, which differ significantly in luminance values, as it only performs pixel-by-pixel comparisons. This requires a significantly large training set with enough variations in it to offset the drawback of the MSE...[Show more]
