Implications and Emerging Trends in Digital Image Processing

The Digital Image processing is the name referred to the techniques and methods applied on input image to transform into output image or extract information from image. With due to rapid growth in the technology, huge data is available in the form of images which need to process for multiple reasons such as automatic text extraction from images, traffic law enforcement using CCTV cameras, processing of medical images for diagnose the diseases etc. The present paper is aimed to explore commonly used techniques in fields of digital image processing. We have also explored different challenges to be faced in different digital image processing applications. The detailed literature review of OCR in Indian languages is carried out and different features are analysed to compare the efficiency of OCR. The current study is aimed to identify emerging trends in digital image processing; particularly we have included future trends in the field of OCR for Indian regional languages
