2. Convolution vs. Correlation

3. Problem with Cross-Correlation

4. 解决办法： Normalized Cross-Correlation: en

• $f[m,n]$ : engery in the image in the area of the image that overlaps with the template
• $t[m,n]$: engery of the template itself, 通过它， you make the cross correlation insensitive to changes in brightness
• so let’s say you had a template that you captured a pattern that you captured with the camera ata some point. It was taken under some lighting conditions and camera gain and so on , and then this pattern appears exactly in its true form, except under different lighting condition, different camera gain and a
