Hand-written digit recognition and classification on edge based on convolution neural network model development

Client Overview

A semiconductor giant offering a wide range of application processors and MCUs with secure connectivity for industries like automotive, industrial & IoT, mobile, and communication infrastructure markets.

Business Challenge

As a successful semiconductor company, client launches multiple processors and MCUs for various industrial application scenarios from time to time. With the launch of one of its processor i.MXRT series, client wanted to introduce machine learning based handwritten digit recognition application on edge into the market. For the same, client was looking for a Machine Learning expert who can help them achieve their launch goal.

VOLANSYS Contribution

VOLANSYS is working as client’s Machine Learning partner by providing deep learning expertise on their edge platform. We helped them develop a solution based on deep neural network to offer applications like digits recognition on number plates, handwritten numeric entries on banking cheques or any forms reducing the manual entries and automating the process for multiple industries.
