Introduction
Nowadays the AI, ML technology are implemented in all financial and insurance corporations. That will reduce a huge man work into a very small tasks and it can be done those thinks in a few minutes. For time consumption and easy access of work AI technology is very helpful for all.
Checkout the below video for signature detection & cropping from any kind fo document even if its cheque, documents, application forms, etc.
How we make it ?
Follow the below mentioned steps to get detect and crop the signature from image
- Image Decoding
- Image Preprocessing
- Signature Detection
- Crop out the Sign
Using the above simple steps we can easy to get the signature from cheque or document
Image preprocessing
It's a very important step in all types of computer vision projects, because it will give you a massive output accuracy. This preprocessing steps involves like edge detection, composing gray scale image from original image. For signature detection we need to fix out white and black background as (127,255) ratio.
Signature Detection
Once preprocessing completed, we need to detect where the signature (Unstructured content) located. Model will make white or black background other than unstructured content. By using this we can easy to get where the signature is located in image.
Signature Cropping
It's almost done when we detect the signature from a document. Using the black and white pixels, we need to remove the white pixels from the image. Then we need to identify the counters of the text available part. Once detected, will make a rectangle on it then crop it using Opencv.
Benefits of Signature Detection
- Validate cheque sign in Banking
- Institutional sign
- Security
- Etc.
