“…The first feature utilizes PCA which has already been used in image fusion and multi-exposure fusion studies, e.g., [7], to give more weight to the dominant pixels of an image. PCA weight maps are extracted for each color channel through their corresponding crosschannel histogram matched channels.…”

“…The second feature, well-exposedness, is initially used by Mertens et al [10] and then adaptively adjusted by Ulucan et al [7] to eliminate over-and/or under-exposed parts of an image, thus to highlight the best exposed parts of it. In this study, the adaptive well-exposedness is utilized given in Eqn.…”

“…To this end, this study proposes a fast and efficient image processing solution to achieve professional-like outputs without destroying image details. The developed method builds upon principal component analysis (PCA) and adaptive wellexposedness [7] feature maps through cross-channel histogram matching, as well as Laplacian [8] and non-local means filtering [9]. Experimental results demonstrate that it is possible to perform lowcost and easier medical imaging in research centers, hospitals and laboratories.…”

The restrictions of accessing high-end microscopes, microscale cameras and high-tech imaging lenses result in a high demand on low-cost microscopes. However, low-cost microscopes are facing with many image capture and quality limitations due to incompatible equipped instrumentation. This study aims at overcoming illumination and contrast problems, color aberration issues, and blur and noise corruption in low-cost microscopes at high image magnification rates. The three color channels of the input image are enhanced via principal component analysis and well-exposedness feature maps by means of cross-channel histogram matching, Laplacian and non-local means filtering. The proposed approach produces sharper, and better color and illumination fixed outputs when compared to existing methods in literature.

Aiming at the characteristics of low brightness of space target image, low contrast with space background and uneven image exposure, a multi-exposure fusion method of space target image based on multi-feature weight was proposed. In this method, contrast features, adaptive optimal brightness features and salience features are used as the basic weights of image fusion weights, and the final weights of image fusion are calculated from these three weights. At the same time, aiming at the low brightness of space target image, local color correction technology is further used to improve the overall brightness of fused image. The experimental results show that compared with the four commonly used multi-exposure fusion methods, the proposed method can achieve better multi-exposure fusion effect on space target images, and the information entropy, spatial frequency and average gradient indexes are improved by 103.8%, 7.69% and 33.72%, singly. IL-Niqe, PIQE and BRISQUE had an increase of 33.99%, 13.57% and 19.07%, respectively.

This paper presents a deep learning approach to detect malicious communication in a computer network. The intercepted communication is transformed into behavioral feature vectors that are reduced (using principal component analysis and stepwise selection methods) and normalized to create training and test sets. A feed-forward artificial neural network is then used as a classifier to determine the type of malicious communication. Three training algorithms were used to train the neural network: the Levenberg-Marquardt algorithm, Bayesian regularization, and the scaled conjugate gradient backpropagation algorithm. The proposed artificial neural network topology after reducing the size of the training and test sets achieves a correct classification probability of 81.5 % for each type of malicious communication and of 99.6 % (and better) for normal communication.
