Classic Perona-Malik(PM) model is usually used to smooth noise for the degraded image. However, to our knowledge, a well-known defect of the PM model is prone to cause ‘staircase effect and blur image fine feature because of the lack of correct diffus

Discrete cosine transform(DCT) is an effective method to extract proper features for face recognition. Discrete cosine transform can only map the resource data to another data field instead of compres
Image registration is widely used in image processing. Researchers have introduced image registration techniques based on the log-polar transform for its rotation and scale invariant properties. It su
Colorization is a well established problem concerning recovering the potential colors of monochrome images. In the past decade several highly effective computer-assisted methods have been proposed for
In this paper we present a method for extracting the best candidate edge combination based on multi-features fusion, aiming at the challenges of accurately locating the Data Matrix(DM) code(hereinafte
A new feature selection method is proposed for high-dimensional data clustering on the basis of data field. With the potential entropy to evaluate the importance of feature subsets, features are filte
In order to improve the general detection accuracy of eye state, this paper puts forward an innovative method for judging human eye state based on PERCLOS. After pretreatment of the eye image, Hough t
In order to realize automatic region matching between source and target images, a multi-source local color transfer algorithm based on texture similarity is proposed. The source and target images are
The patch matching of the traditional Nonlocal means(NLM) filter mainly depends on structure similarity and cannot adapt to the patch rotation or mirroring transformation. Therefore, designing a measu
The integrality of moving objects is the basis for video-based object tracking and action analysis. But it often becomes unreliable as a result of shadow elimination when the object has similar proper
Compressed sensing based Magnetic resonance(MR) image reconstruction can be done by minimizing the sum of least square data fitting item, the Total variation(TV) and l1 norm regularizations. In this p
