Offline marathi handwritten character recognition using SVM classifier based on cloud computing: Review

Freeman chain code histogram and Gradient feature extraction techniques are better because freeman chain code approach is robustness to small variation and easy to implement and the gradient technique can be easily used to gray scale images and are robust against image noise and edge direction fluctuation. SVM classifier is better than KNN and ANN classifier because of its complexity of training, flexibility, classification accuracy and complexity which is given bellow.
