Claim One:
1. An apparatus comprising: a processor; and a memory comprising instructions, wherein the instructions cause the processor to perform an image retargeting quality assessment comprising: obtaining an original image and a retargeted image, wherein the retargeted image is produced by performing a retargeting algorithm on the original image; and comparing the original image and the retargeted image in a frequency domain and in a spatial domain to determine local content changes between the images, wherein local content changes between the images is determined by: determining an average Sum of Squared Differences (SSD) of pixel values in International Commission on Illumination (CIE) L*a*b* (CIELAB) color space between the original image and a reconstructed image created using image patches from the retargeted image; determining the average SSD of pixel values in CIELAB color space between the retargeted image and a reconstructed image created using image patches from the original image; and adding the average SSD of pixel values between the original image and the reconstructed image to the average SSD of pixel values between the retargeted image and a reconstructed image.
