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 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.
