Image registration is a key technique in pattern recognition and image processing
and it is widely used in many application areas such as computer vision
remote sensing
image fusion and object tracking. A method for image registration combining Mexican-hat wavelets and pseudo-Zernike moments is proposed. Firstly
feature points are extracted using scale-interaction Mexican-hat wavelets in the reference image and sensed image respectively. Then
pseudo-Zernike moments are used to match them and classical RANSAC used to eliminate the wrong matches. And then
the well match points are used to estimate the best affine transform parameters by least squares minimization. At last
the sensed image is transformed and resampled to accomplish the image registration. The experiments indicate that the proposed algorithm extracts feature points and matches them exactly and eliminates wrong matched points effectively and achieves nice registration results. 2012 TSI Press.

Image enhancement and image de-noising have being the important research contents of image academic and engineering field
and the partial differential equations have been widely applied to computer vision. The paper applies the thoughts of partial differential equations
puts forward a new improved method of image enhancement. This method can enhance not only the dark images but also the bright images
making the details hidden in the dark background and the bright background very clear. The application scope is wider
and the visual effect is better. This paper uses the finite difference method to discrete the partial differential equations
and combines with the heat equation. It calculates simple
runs fast
and provides a guarantee for real-time video image enhancement processing. 2010 IEEE.

This paper presents an intelligent video surveillance system. The system is composed of one or more nodes flexibly according to the application scenarios such as private properties
banks and museums. Each node is an autonomous vision-based device capable to perform intelligent tasks. It is able to digitize and compress the acquired analog video signals in MPEG-4 standard and then transmit the compressed video stream to the control center. At the same time
the node makes use of a statistical approach for real-time detecting moving object and online alarm generation to enable a single human operator to monitor activities over a complex area using a distributed network of active video sensors. The node is implemented on a platform with high performance to ensure that the algorithm is able to run in real-time. Applications demonstrate that the intelligent system has an excellent performance in many scenarios to help people make decisions more accurately and rapidly. 2010 IEEE.

TDI CCD is widely used in the high speed imaging camera
glimmering vision and robotic vision fields
because of its excellent operation. But TDI CCD's high ordering price and easy damage in circuit testing usually limit its application in real projects. In this paper basing the simulation of both the photoelectronic character and electronic character
a instrument is described in details. 2009 IEEE.

Partial occlusion is a difficult problem in computer vision since whether the object is changed or occluded is ambiguous
especially when distinguishing it only from the object boundary. In this paper
we proposed a novel idea to solve this problem by taking shape matching as a morphing processing. A mass-spring model is constructed from the point set which is sampled from a template (or reference) object boundary by moving it to a target object which is deformed and/or occluded. From the morphing processing
sufficient information can be obtained and an accurate detection of occlusion is performed. By using of the proposed method
the application scope of occlusion detection is expanded while other method cannot be performed which need color
texture
or motion information. The experiments performed on synthetic and real world images proved the satisfactory performance of the proposed method. 2009 IEEE.
