# Captcha Solver

Captcha solver using **YOLO v3**. Has an accuracy of **98.166%** on the test dataset.

 

* The trained weights and config file can be found **[here](https://drive.google.com/open?id=1_OH7LXR82GEeDKAa7ntEuI_HpG0e3WkH)**.

* Save the trained final weights, yolov3 configuration file and captcha names file in a folder named data. 

* The annotation of dataset is done manually using BBox Label Tool. We find the object's centre x and y coordinates and normalized width and height.

## Example of data annotation
