Abstract

Computer based patient monitoring systems help in keeping track of the patients’ responsiveness to the treatment over the course of the treatment. Further, development of these kind of healthcare systems that require minimal or no human intervention form one of the most essential elements of smart cities. In order to make it a reality, the computer vision and machine learning techniques provide numerous ways to improve the efficiency of the automated healthcare systems. Image super-resolution (SR) has been an active area of research in the field of computer vision for the past couple of decades. The SR algorithms are offline and independent of image capturing devices making them suitable for various applications such as video surveillance, medical image analysis, remote sensing etc. This paper proposes a learning based SR algorithm for generating high resolution (HR) images from low resolution (LR) images. The proposed approach uses the fusion of deep convolutional neural network (CNN) and support vector machines (SVM) with regression for learning and reconstruction. Learning with deep neural networks exhibit better approximation and support vector machines work well in decision making. The experiments with the retinal images from RIMONE and CHASEDB have shown that the proposed approach outperforms the existing image super-resolution approaches in terms of peak signal to noise ratio (PSNR) as well as mean squared error (MSE).
