SWT based Resolution Enhancement Technique for WCE Images

Wireless capsule endoscopy is an emerging technique in medical field used for diagnosing diseases in gastrointestinal tract of human body. An efficient image resolution enhancement technique is proposed to overcome low resolution image limitation of wireless capsule endoscopy to enhance the diagnosing rate and reduce the stress of doctor. The proposed technique is a combination of stationary wavelet transform and bicubic technique, which provided good results compared to other enhancing techniques. The proposed technique provided good subjective quality compared to conventional bicubic method and objective quality in term of PSNR and SSIM compared to other techniques.
