Count Coins by AI Object Detection in Power Apps
Till date I use Piggy Bank to save coins (Imagine my salary :P). Every 3 months I count them and give it to some nearby shop. Thought how AI object detection can help me to count the coins. Last one month I was up to this PoC. After lots of training and failed attempts to create a model (AI Object Model) finally I found a satisfactory result.
Here are few observations:
1. It did not work well when I downloaded 5, 10, 20 and 50 cents image from Internet and create the model. I have downloaded 200+ Images separately (some were mix) but no use.
2. It expects multiple coins in one image and the quality of the image should be crisp.
3. Coins are reflective so it is very tough to take images by camera without any reflection.
4. A lot of coins can be confusing for the AI detection because in that case we need to take images (shots by camera) from a distance/height so every coin treat as 5 cents (the smaller one)
5. The more you train model the more you get good result. I have not trained the model from tail side always keep head side.
6. There are variety of edition of a same coin so needs more training for it.
7. 20 cent and 50 cent coins look alike and 5 cent and 10 cent is look alike so it is not giving right result sometime.
