Following are the unnormalized features I extracted for 1080454109_f73229da8b_z.jpg, an image of fall foliage in the Train/nonsunset folder. First is the version in which I centered the grid and ignored the border pixels when then the number of blocks (e.g., 7) did not divide the image size evenly. Second is one that starts in the upper-left corner of the image, ignoring extra pixels on the bottom and right if needed.
