In this research, presented an underwater image enhancement (IE) making use of discrete cosine transform (DCT) with dynamic histogram equalization (DHE) algorithm. The main issue in IE underwater images are blur impact, low-contrast, nonuniform illumination, because of turbulence in flow of water. In underwater images, it impacts the scattering of light from a few particles of various sizes, low force caused by low visibility conditions, suspended development particles. In this approach, firstly take RGB to YCBCR format for further processing. The new result is applied on peak signal Noise Ratio (PSNR) and Entropy. This calculation is contrasted and three calculations, to be specific DCP[1], brightness bi histogram equalization(BBHE), Contrast Enhance method. The proposed algorithm decribes that better performance as compared to other algorithms.
Current pose estimation methods make unrealistic assumptions regarding the body postures. Here, we seek to propose a general scheme which does not make assumptions regarding the relative position of body parts. Practi...

This paper presents optimized connection searching method based on region filling algorithms. The proposed method is optimized using the heuristic and is intended for maze-solving. In specific cases, the proposed algorithm performs better than variants which do not use heuristic and it depends on the maze structure and position of the starting and ending pixel.

In present scenario whole world is moving towards digital communication for fast and better communication. But in this a problem arises with security i.e. when we have to transmit information (either data or image) over internet or to store information at any random location then its security is very important. To protect our information from hackers we use a technique i.e. Encryption. In this paper we use image as information and use different types of encryption techniques to encrypt it and protect it from hackers. After that we find various parameters from each image encryption technique and then compare each technique's parameters from one another. After that we search for the best result and then proceed forward with that technique for future scope.

Infrared signal processingalgorithms and architectures are important for the development of a high performance infrared imaging systems. Infrared signal processing deals with two types of processing sensor signal processing and infrared imageprocessing for contrast enhancement and target detection. The sensor signal processing primarily deals with non uniformity correction for infrared sensors. Assessing the quality of the Infrared video frame is a complex and firm process since human's opinion is affected by physical and psychological parameters. Infrared Video frame quality assessment plays an important role in the field of video processing. Structural Similarity Index has become a standard among image quality metrics. It is a framework for quality assessment based on the degradation of structural information of video frame. In this paper SSIM values are computed and compared for Infrared video frames by applying different edge detection approaches by using different color models to assess the quality of the frames. Experimental results comparisons demonstrate the effectiveness of the proposed method.

The study of substances with a crystal structure is a complex multi-step process. The key step in the crystalline substance analysis is the unit cell parameter estimation. The estimation of the crystal lattice unit cell parameters is a particular problem that involves the search of the crystal lattice model’s parameters according to the information which can be extracted from the substance. In these recent times, the most accurate information about the substance structure can be obtained with the electron microscope whose linear resolution is high enough to observe the atomic structure of a substance. The problem of parameter estimation in this case means the reconstruction of the three-dimensional crystal lattice with 2-dimentional images received by an electron microscope, and the estimation of the crystal lattice unit cell parameters by reconstructed lattice. In the previous papers the crystal lattice parametric identification algorithms based on solving the local optimization problem were presented. However, the analysis of a large crystal lattice database requires a lot of computations. In this paper, a high-performance crystal lattices parametric identification algorithm using the CUDA technology is proposed. The investigation of the algorithm effectiveness is carried out on the GPU GeForce NVidia GTX 1070 Ti. With data dimension more than 32 translations the acceleration is higher than 70. The algorithm runs more efficiently at the use of a large number of CUDA-blocks.

By a car license plate recognition, we mean a software system processingimages and providing an alphanumeric transcription of car plates included in an image. We divide the task into four sub-tasks: license plate localization, license plate extraction, characters segmentation and characters recognition. All four sub-tasks are discussed in the context of standard approaches and own solution based on a chain of standard and soft computing imageprocessingalgorithms is presented. In this chain, the F-transform approximate pattern matching algorithm plays the crucial role. For the solution, we presented recognition ability for a dataset which includes 500 images with difficult conditions.

One of the key technologies of the large-size electronic whiteboard is pen locating, but most existing technologies have their weaknesses. In this paper, a pen locating algorithm and its prototype are proposed. Using Spatial-based watermark embedding method, the pen-locating algorithm generates watermarked blocks by embedding watermark information into the background image on the screen. The pen detects the watermarked blocks on the screen and when the watermarked blocks are detected, the pen can be located through the analysis of the image block location and the distance between the pen and the image block. The algorithm is tested by simulation and the locating error of the prototype system is 1.7 pixels approximately.
