[IEEE 2018 International Conference and Exposition on Electrical And Power Engineering (EPE) - Iasi (2018.10.18-2018.10.19)] 2018 International Conference and Exposition on Electrical And Power Engineering (EPE) - Metaheuristic Algorithms based Multi-objective Optimization for Image Segmentation
摘要： In this paper a multi-threshold image segmentation procedure based on nature-inspired multi-objective optimization is proposed. The Particle Swarm Optimization, Black Hole and Gravitational Search algorithms were adapted for multi-objective optimization. The Root Mean Square Error and the number of segmented regions were used as optimization criteria. The three procedures were applied for human silhouettes detection in video sequences and the obtained results are compared. Concerning the algorithms performances, the experiments revealed that the results of multi-objective Black Hole algorithm based segmentation are better than those of the other two algorithms, at least for the test images used in this experiment.

摘要： Information is the key in today’s world and secure transmission is a must. The cryptography is about making cipher and keys management. They assume cipher can be detected and must be strong enough to decipher, but what if the cipher/information is not visible? The cipher would not be detected. The steganography makes this enable. This paper discusses how to hide an MP3 file in a digital image such that it becomes difficult to conclude about the existence of the hidden audio data. Here we utilize the k-LSB of pixels in an image to embed audio data bits into a selected pixel. The pixels are so chosen that the distortion in the image would be minimized due to embedding. This requires comparing all the possible permutations of pixel values, which may lead to exponential time complexity. For faster computation Whale optimization algorithm was used to find the most optimal solution.
