Kamble et al. (2015) proposed the Rectangle Histogram Oriented Gradient representation as the source for extraction of character. These algorithms need a small number of easy arithmetic operations per image pixel that formulates them appropriate for real-time applications. The dataset includes of 8000 models each one of 40 essential handwritten Marathi characters. Expected results by using classification methods are Support Vector Machines (SVM) and feed-forward Artificial Neural Network (FFANN) are presented.
Keysers and Daniel (2017), proposed a Google’s online handwritten identification scheme that presently supports 22 characters and 97 languages. The scheme centre of attention is on fast, high-accuracy text access for mobile, touch-enabled devices. They make use of an arrangement of state-of-the-art apparatus and merge them with novel additions in a flexible frame. This construction allows them to simply transmit developments involving languages and characters. They present a general summary of the scheme architecture and the new apparatus, like unified time- and position-based input interpretation, trainable segmentation, minimum-error rate training for feature extraction, and a cascade of pruning strategies, by achieving the experimental results for different setups.
Chaudhuri and Chandranath (2017) proposed the recognition and processing of struck-out texts in unrestricted offline handwritten file images. A feature extraction method is-based on two-classes, first one is SVM classifier utilized to detect moderate-sized struck-out parameters. The skeleton of the text element is measured as a graph and the strike-out stroke is recognized by using a constrained shortest path algorithm. They selected only 500 pages of documents and achieved an overall F-Measure of 91.56% (91.06%) in English script for struck out text detection.
Hegadi (2012) discussed an approach for recognition of handwritten as well as printed Kannada numerals. The planned framework involves the three main segments, such as pre-processing, feature extraction and classification. The numeral images are preprocessed and noise removal technique is applied, in the classification stage, a multilayer feed forward neural network classified ten handwritten numerals into distinct classes. The recognition rate of proposed method is impressive.
