Standard methods used in the encryption and decryption process are implemented to protect confidential data. These require many arithmetic logical operations that negatively affect performance of process. In addition, they use private keys a specific length, addition fixed length data block encryption, which may provide possibility penetration these methods, thus decreasing level security. this...

The dependence on computing machines and utility of information has been growing tremendously in the last few decades. As a result, evolving effective techniques for storing and transmitting the ever increasing volumes of data has become a high priority issue. Image compression addresses the problem by reducing the amount of data required to represent a digital image. The underlying basis of th...

Hand posture estimation attracts researchers because of its many applications. Hand posture recognition systems simulate the hand postures by using mathematical algorithms. Convolutional neural networks have provided the best results in the hand posture recognition so far. In this paper, we propose a new method to estimate the hand skeletal posture by using deep convolutional neural networks. T...

Potato image segmentation is an important part of image-based potato defect detection. This paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on Genetic Algorithm (GA) optimization and morphological operators. The proposed potato color image segmentation is robust against variation of background, distance and ...

Visual cryptography is a powerful technique which combines the notions of perfect ciphers and secret sharing in cryptography with that of raster graphics. A binary image can be divided into shares which can be stacked together to approximately recover the original image. Unfortunately, it has not been used much primarily because the decryption process entails a severe degradation in image quali...

In this paper, we present a new robust hybrid algorithm combining successively chaotic encryption and blind watermarking of images based on the quaternionic wavelet transform (QWT) to ensure secure transfer digital data. The calculations different evaluation parameters have been performed in order determine robustness our certain attacks. application CFA (Color Filter Array) images, allowed us ...
