Magnetic Resonance Imaging (MRI) is a medical indicative test utilized for taking images of the tissue points of interest of the human body. During image acquisition, MRI images can be damaged by many noise signals such as impulse noise. One reason for this noise may be a sharp or sudden disturbance in the image signal. The removal of impulse noise is one of the real difficulties. As of late, numerous image de-noising methods were produced for removing the impulse noise from images. Comparative analysis of known and modern methods of median filter family is presented in this paper. These filters can be categorized as follows: Standard Median Filter; Adaptive Median Filter; Progressive Switching Median Filter; Noise Adaptive Fuzzy Switching Median Filter; and Different Applied Median Filter. The de-noising technique performance for each one is evaluated and compared using Peak Signal Noise Ratio, Structural Similarity index Metric, and Beta metric as quantitative metrics. The experimental results showed that the latest de-noising technique, Different Applied Median Filter (DAMF), produced better results in removing impulse noise compared with the other de-noising techniques. However, this filter produced de-noised image with nonlinear edges in high-density noise. As a result, noise removal from images is one of the low-level images processing which is considered as a first step in many image applications. Therefore, the efficiency of any image processed depends on the efficiency of noise removal technique.

“…The implementation is executed in MATLAB R2015b on windows 7 laptop with Intel Core I5 Processor, 4.0 GB RAM and 500 GB Hard Disk. The processed multimodality medical input images are gathered from harvard medical school [16] and radiopedia.org [17] [2], [3]. A high score indicates a superior performance for first four metrics and least time is best for final metrics.…”

:Multimodal medical image fusion technique is one of the most significant and useful disease investigative techniques by deriving the complementary information from different multimodality medical images. This research paper, proposed an efficient multimodal medical image fusion approach based on deep learning convolutional neural networks (CNN) for fusion process. Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and Positran Emission Tomography (PET) are the input multimodality medical images used for the experimental work. In the proposed technique, a siamese convolutional network is adopted to create a weight map which integrates the pixel movement information from two or more multimodality medical images. The medical image fusion process is carried out in a multiscale manner via medical image pyramids to be more reliable with human visual insight. In addition, a local comparison based strategy is applied to adaptively correct the fusion mode for the decomposed coefficients. An experimental result of proposed fusion techniques provides the best fused multimodal medical images of highest quality, shortest processing time and best visualization in both visual quality and objective assessment criteria.

“…There is a lot of scope for applying the Discrete Wavelet Transform (DWT) in many fields like Bio-Informatics, Compression of data, images and videos, Pattern recognization etc. Using wavelets in Image fusion had shown that the 2-D DWT is more efficient [19] than the Discrete Cosine Transform (DCT) and it is noted that the 2-D DWT with 9/7 Daubechies channel had shown high PSNR and clear intertwined picture [10]. The principle thought of our calculation is that: (1) Two pictures are selected prepared are re-sampled to one with a similar size; and (2) Individually these images are deteriorated into the sub-images utilizing forward wavelet change, which have a similar goals at similar dimensions and different goals among various dimensions; and (3) Fusion is applied dependent on high-recurrence sub images of decayed pictures; lastly the outcome picture is acquired utilizing opposite wavelet change.…”

In image processing, image fusion is separating the data from multi-source pictures and has a major scope in processing an image. A completed fused image is acquired by averaging the two images. Wavelet transform based algorithm is proposed to enhance the image, wherein two images to be prepared are right off the bat deteriorated into sub-images with various recurrence, and after that the information is fused using these images specific paradigm, lastly these sub-images are reconstructed into the outcome image with copious information. Correlation and SNR parameters are utilized to analyze the fused images.
