Hand Gesture Recognition  

============================

## Detects finger movements of hands and shows appropriate output.    

  

#### Steps:  

+ *Segment hand region from a real-time video sequence*  

  - Background Subtraction  

  - Motion Detection and Thresholding  

  - Contour Extraction

  

+ *Count fingers*  

  - Get convex hull of the segmented hand region and compute the most extreme points in the convex hull  

  - Get center of palm using extremes points  

  - Using center of palm, construct a circle with the maximum Euclidean distance as radius  

  - Perform bitwise AND operation on thresholded hand image and the circular ROI  

  - Compute count of fingers using the finger slices obtained in previous step  

#### To run the file use:    **python sudo.py**  

![#f03c15](https://placehold.it/15/f03c15/000000?text=+) `Memory Intensive Operation`  

![#f03c15](https://placehold.it/15/f03c15/000000?text=+) `This script creates screenshot for every frame captured and stores it in directory 'screenshots'`  

![#f03c15](https://placehold.it/15/f03c15/000000?text=+) `Hence, there is a little delay during frame capture`  

### To-Do List:  

- [x] Segment hand region

- [x] Detect numbers using count of fingers

- [ ] Detect characters using finger motion

- [ ] Capture words using word motion

- [ ] Automate tasks with each character / word
