To overcome the deterioration of azimuth resolution caused by errors of monopulse response curve (MRC) in practical processing, this paper proposes an auto-focusing algorithm for monopulse imaging technique. By applying iterative steps, this algorithm automatically extracts the echo signals of isolated strong scatterers from the received data, and employs them to accurately estimate the actual MRC...
With network performance being highly dependent on the actual traffic, studies have shown that traffic is self-similar and long-range correlation in Network on Chip (NoC). The self-similarity of NoC traffic depends not only on the input sequence, but also changes with the processor algorithm on chip. In this paper, we improved firstly the existing method for generating sample traces of self-similar...
Sparse Representation-based Classification (SRC) is a newly introduced algorithm for face recognition, notable for its robust performance to occlusions and corruptions. Local Binary Patterns (LBP) is a very powerful method to describe the texture and shape of images. In this paper, we propose a novel method for facial expression recognition based on sparse representation of LBP features. Extensive...
In this paper, a method of blind source separation (BSS) is proposed based on wavelet denoising. This method firstly makes wavelet transform (WT) to the observation signals, and then adopts a uniform method which combines signal whitening and maximum information algorithm to obtain the separate signals which approach to the source signals. Simulations show this method could achieve better performance...
Sparse representation in compressed sensing is a hot topic in signal processing and artificial intelligence due to its success in various applications. A general classification algorithm based on sparse representation theory named Sparse Representation Classification (SRC) was successfully applied in face recognition. In this paper, we research the issue of facial expression recognition (FER) via...
FR is a steganalysis algorithm based on frequency domain for F5. It has been widely used because of its high-capacity and robustness. In recent years, many scholars have engaged in the field. In this paper, It is proposed for a JPEG information hiding algorithm of resisting F5(JHRF). By embedding secret information into IPEG image by rules, JHRF can deal effectively with abnormal data and get better...
