Image quality evaluation is very important. In applications involving signal transmission, the
Reduced-or No-Reference quality metrics are generally more practical than the Full …

In the construction of the knowledge system, visual perception is the primary means of
acquiring knowledge. Thus, it is very essential to solve the problems related to visual …

In this paper, we present a new adaptive contourlet-based steganography method that hides
secret data in a specific or automatically selected cover image. Our proposed …

One of the important requirements in image retrieval, indexing, classification, clustering and
etc. is extracting efficient features from images. The color feature is one of the most widely …

Capacity is one of the most important parameters in image watermarking. Different works
have been done on this subject with different assumptions on image and communication …

Mostly the embedding capacity of steganography methods is assessed in non-zero DCT
coefficients. Due to unequal distribution of non-zero DCT coefficients in images with different …

In steganography, the cover medium is widely treated as a mere container for the embedded
information, even though it affects the stego-image quality, security, and robustness. In …

The feature engineering approach determines features using expert knowledge about the
data input and feature extraction method. Therefore, this approach obtains features that are …

This work presents a new hardware cache management approach for improving the cache
hit ratio and reducing the bus traffic. Increasing the L1 cache hit ratio is a crucial aspect of …

The video quality analysis is very important in today's video broadcasting and transmission
quality control because the quality is a key factor in customer satisfaction. This paper …
