چکیده
Conventionally, radiographic images have low contrast due to less illumination of the light. X-Ray imaging is one of the least expensive, easy to read method used by most of the doctors and radiologists. A method based on dual tree complex wavelet transform (DTCWT), contrast limited adaptive histogram equalization (CLAHE) and Wiener filter is proposed for enhancing the visual quality of the X-Ray images. Quantitative analysis of proposed algorithm is done by evaluating MSE, PSNR, SNR and Contrast Ratio (CR).

Modern medical image diagnostic are often based on X-ray, computerized tomography and magnetic resonance imaging technique. The raw data delivered by such imaging devices more often than not take several mega-bytes of disk space. The diagnostic images for radiology interpretation must be efficiently stored and transmitted by physician for the further medical or legal purposes. Digital medical i...
متن کاملEnhancing performance of Image Retrieval Systems using Dual Tree Complex Wavelet Transform and Support Vector Machines
This paper presents a novel image retrieval system (SVMBIR) based on dual tree complex wavelet transform (CWT) and support vector machines (SVM). We have shown how one can improve the performance of image retrieval systems by assuming two attributes. Firstly, images that a user needs through query image are similar to a group of images with the same conception. Secondly, there exists non-linear...
