Finding Corresponding Points between 2 Images

Programmed from scracth using python

Algorithms

• Harris Corner Detector
• Normalized Cross Correlation

How to use this code

Finding Corners using HCD Algorithm

 python3 harris.py --image image_name --sigma sigma_value --threshold threshold_value   

Example:

 python3 harris.py --image images/01.png --sigma 3 --threshold 0.1

Finding Corresponding Points using HCD and NCC Algorithms

python3 demo.py \  
       --image1        image1_name    \  
       --image2        image2_name    \  
       --sigma         sigma value    \  
       --threshold_h   threshold value for harris corner detector \  
       --threshold_d   threshold vaşue for point descriptor       \  
       --min_dist      minimum distance value between points      \  
       --wid           wid value                                  \  
       --graph         graph type [line or point]                       

Example 1: graph = line

python3 demo.py  \
       --image1 images/01.png  \
       --image2 images/02.png  \
       --sigma 3               \
       --threshold_h 0.05      \
       --threshold_d 0.5       \
       --graph line

Example 2: graph = point

python3 demo.py  \
       --image1 images/01.png  \
       --image2 images/02.png  \
       --sigma 3               \
       --threshold_h 0.05      \
       --threshold_d 0.5       \
       --graph point
