Medical Image Fusion using Hybrid DCT-DWT based Approach
Abstract: During a clinical study or diagnosis, many sources of information are available to the clinician: different imaging modalities, and different tools to better study the structure or pathology. The clinician must synthesize these different pieces of information in order to perform accurate and reliable diagnosis and / or treatment. However, this synthesis can be long, tedious and remains highly dependent on the operator who takes care of it. In this context, image fusion appears as a new tool to help diagnosis; making the task easier for the doctor by providing a simpler fusion tool than mental fusion. As part of this work, the paper presents a comparative study of fusion techniques, the first one based on the discrete wavelet transform (DWT) and the second one based on discrete cosine transform (DCT) and the third one that is new based on the hybridization of DCT and DWT.

Fusion based Hybrid Cooperative Spectrum Sensing in Cognitive Radio Framework
Abstract: Cognitive radio sensor network (CRSN) demands energy efficient and a cost effective cooperative spectrum sensing techniques which perform well in fading and shadowing environment. The work presented in this paper is the Fusion technique for hybrid cooperative spectrum sensing using AND fusion of three secondary users for decision making. Transmission by primary user is how many times detected at secondary users shows the probability of detection. The results of simulation shows that probability of detection improves using AND fusion for the three secondary users. Performance of proposed system is evaluated using SNR, probability of false alarm and Sensing Time.
