Barcode Detection using OpenCV-Python

Almost all the products and items that exist into the market today have a unique code or an ID associated with them. This special ID is what we call as Barcode. Barcode Detection is very common and is a necessity today as it makes our job easy. One can just scan the code and easily get all the details of the product. It's becoming even more popular and prevalent day by day. The algorithm involves mainly 4 steps: calculation of Scharr gradient, making the image blur, kernel application and erosions & dilations. After implementing this algorithm, we made a Barcode Detection Android App.
