Stamp and Signature Detector

Stamp and Signature Detector is a Machine Learning based application that detects and classifies stamps and signatures. It is based on Multi-Object Detector, which detects and classifies the Stamp or Signature on a document that is processed in the Application.

The Application requires training for the stamps and signatures that are to be detected. To train the application, at least 150 images for each stamp or signature are required

Modern object detectors and classifiers require heavy computing power to train the models as well as run the models for testing. Our goal was to build such a model that is light weight, requires less computing power comparatively, and provides best results.

The Stamp and Signature Detector application consists of combination of Support Vector Machine (SVM) and Histogram of Gradient (HOG). SVM is a supervised learning model with associated learning algorithm that analyze data for classification and regression analysis. HOG is a feature descriptor, which has the capability to extract features using CPU only.

The Application requires training for the stamps and signatures that are to be detected. To train the application, at least 150 images for each stamp or signature are required
