Dpy_sift_intro.markdown14 In last couple of chapters, we saw some corner detectors like Harris etc. They are
16 obvious because corners remain corners in rotated image also. But what about scaling? A corner may
17 not be a corner if the image is scaled. For example, check a simple image below. A corner in a small
18 image within a small window is flat when it is zoomed in the same window. So Harris corner is not
34 different scale. It is OK with small corner. But to detect larger corners we need larger windows.
38 gaussian kernel with low \f$\sigma\f$ gives high value for small corner while guassian kernel with …
39 \f$\sigma\f$ fits well for larger corner. So, we can find the local maxima across the scale and spa…
