mattes / epeg
Insanely fast JPEG/ JPG thumbnail scaling with the minimum fuss and CPU overhead. It makes use of libjpeg features of being able to load an image by only decoding the DCT coefficients needed to reconstruct an image of the size desired.

rg4sun / RG_DCT
Implementation and Performance Analysis of DCT Steganography Algorithm. Tests found that it has excellent imperceptibility (PSNR all above 40). When encountering noised images, the error rate of watermark extraction is low, indicating certain robustness. By introducing the scaling factor, the best embedding effect can be obtained for the specific carrier and watermark.
