The image is captioned as "Original 512 x 512 grayscale image, with 256 gray levels for each pixel, before fractal compression.".
So, if what your saying is true the caption is wrong? Are you saying it is the first stage of decompression? That this is the input data to the decompressor?
I'm assuming therefore that the compressor actually does use a full undownsampled (not blocky) image as it's input. Or uses it as part of it's iterative compression process. Is that correct?
- andyNH 12y agoGood point. The caption for Figure 2 is wrong. The picture is of the first step in decompression of a 512 x 512 image. A pity you do not actually see the original that they refer to.
- mrow84 12y agoI think that actually the caption is "correct", and they must have simply included the wrong image, because the text says "Figure 2 shows the original digital image of Balloon, which is of dimensions 512 pixels by 512 pixels, with 256 gray levels at each pixel."
