Generate adversarial networks (GAN) is a popular method, which can be widely used in numerous research areas, such as computervision, natural language processing, and time series synthesis. However, few references are proposed to give a comprehensive review on GAN based methods. This paper aims to provide a detailed review of GAN based algorithms on computervision tasks, such as image style transfer, image/video generation, image matting, andimage super-resolution. Furthermore, we conclude the evaluation metrics for those tasks to show the effectiveness of GAN based on method. Our review can help beginners recognize the GAN based methods and give a brief introduction on how to apply them to their tasks.

Two-dimensional mathematical modeling and simulations are carried out to observe a reference and a binary star in the absence and presence of a Kolmogorov turbulence via ground-based optical telescopes. This involve the quantitative assessment of the modulation transfer function (MTF) of a reference star, the Fourier magnitude (FM) and the autocorrelation function (AUT) of a binary star. As a result of this assessment a second degree polynomial equation is introduced to describe the average MTF of a reference star and the average FM of an image of a binary star that observed by different telescope diameters. The results also indicate that the height of the secondary peaks of the A UT remain constant despite of the strength of atmospheric turbulence and the diameter of the telescope while the width of these peaks change significantly.

Information security has been one of the major concerns in the field of communication today. Steganography is one of the ways used for secure communication, where people cannot feel the existence of the secret information. The need for parallelizing an algorithm increases, as any good algorithm becomes a failure if the computation time taken by it is large. In this paper two parallel algorithms-parallel RSA (Rivest Shamir Adleman) cryptosystem with 2D-DCT (Discrete Cosine Transformation) steganography and parallel chaotic 2D-DCT steganography-have been proposed. The performance of both algorithms for larger images is determined and chaotic steganography is proved to be an efficient algorithm for larger messages. The parallelized version also proves to have reduced processing time than serial version with the speed-up ratios of 1.6 and 3.18.

This paper deals with the improvement of free energy computing in segmentation algorithm according to the analysis of image Segmentation Algorithm Based on Boltzmann Theory (ISABT) and a new one is proposed. It is proved by comparative experiments that performance indexes of the new algorithm are considerably improved. The parallel processing method of the algorithm which is applied to multiprocessors is presented for solving the real-time problem, and then its feasibility is verified by experiments. The experiment shows that the improved ISABT with rapid parallel imageprocessing greatly enhances the speed of segmentation with its segmentation effect assured. Compared with the original algorithm, the new one may reach a speed of 20ms/F for 480x320 image on the processing platform including eight pieces of TMS320DM642, and it basically meets the real-time requirement for robot visual processing.

This paper presents a super-resolution algorithm specifically aimed at the document processing. There are some particular characteristics in document image, such as step edge, fixed pattern etc. And in the practical application scenarios, such as scanner optimization, electronic books and so on, all of them propose a real-time requirement to the algorithm. For these scenarios, the existing interpolation-based and learning-based super-resolution methods have their limitations. Based on the idea of stratification, this paper proposes the application of guided filter in document matting, and divides the image with this approach into three layers: foreground color, background color and text edge. Interpolated algorithm are used for foreground and background parts to maintain their smoothness and high fidelity of color. For the key structure information contained in the edge layer, the super-resolution reconstruction is performed using the training-based algorithm. The algorithm has the characteristics of color fidelity, edge preserving, clear structure, and efficient training, which can meet the application requirements of document processing well. This paper provides a detailed description of the algorithm, and at the same time provides sufficient comparison and quantification experiments to demonstrate the effectiveness of the algorithm.

Skin cancer is a form of cancer that is most common among Caucasians and is rapidly increasing year by year. Melanoma is the most dangerous type of skin cancer making it the world's 17th most common cancer type which is 1.8% of all cancer patients globally. It is vital to detect Melanoma at its early stages to cure the patient without letting the cancer grow further. The proposed solution is to develop a system that can detect Melanoma by analysing the dermoscopic images while extracting Asymmetry, Border Irregularity, Colour, Diameter (ABCD) features and other salient dermoscopic features which are more often visible in Melanoma skin lesions. Different classification methods are also being evaluated to identify which classifier works best with the dermoscopic features extracted in the feature extraction stage so that the highest accuracy could be obtained when diagnosing Melanoma. Therefore, when a dermoscopic image is given to this proposed system it will output whether the patient is diagnosed with Melanoma along with the confidence level of the diagnosis result at which the model performed the diagnosis based on the various dermoscopic features extracted from the lesion.

image degraded by haze is a critical aspect in today's environment while getting a high-quality haze-free image remains an important task in computervision. In recent year, many works have been done to improve the visibility of image taken under bad weather. Conventional designs use multiple image and/or single image to deal with haze removal. In this paper, we use a simple but effective prior, a variation of distance (VoD) prior, to estimate the transmission map and remove haze from a single input image. The VoD prior is developed based on the idea that the outdoor visibility of images taken under hazy weather conditions seriously reduced when the distance increases. The thickness of the haze can be estimated effectively and a haze-free image can be recovered by adopting the VoD prior and the new haze imaging model. Our method is stable to image local regions containing objects in different depths. Our experiments showed that the proposed method achieved better results than several state-of-the-art methods, and it can be implemented very quickly. Our method due to its fast speed and the good visual effect is suitable for real-time applications. This work confirms that estimating the transmission map using the distance information instead the color information is a crucial point in image enhancement and especially single image haze removal.
