Abstract
Medical imaging is an active and developing field that has an impact on recognition, diagnosis and surgical planning of the disease. The image compression is introduced in the medical imaging for decreasing the redundancies to avoid storage and bandwidth related problems. In this research, Discrete Wavelet Transform and Recurrent Neural Network based compression techniques are used through brain images for achieving better compression rate with less loss. The region growing and otsu thresholding are used to separate the ROI image and Non ROI image. The DWT and RNN are used for the ROI and non ROI portions of the medical image. Additionally, the local attributes of RNN is enhanced by Gravitational Search Algorithm and Particle Swarm Optimization. The performance of this proposed method is calculated as peak signal to noise ratio, mean square error, compression ratio and space saving percentage. The existing techniques used to compare the proposed method are Fractional Order Darwinian PSO, Quasi Fractal and Oscillation Method and Burrows Wheeler Transform—move to front transform. The PSNR of the proposed method is 35.2362 dB which is high when compared to the existing methods.
