When integral imaging systems work in their conventional configuration, the reconstructed images are pseudoscopic. The two-step pickup process is capable of giving an orthoscopic image, but it involves black zones, which affect the viewing angle. We analyze the black zones on the elemental images. The improved two-step pickup process is proposed to solve this problem, and the mathematical models of...
Accurate liver segmentation from abdominal computed tomography (CT) images is one of the most important steps for computer aided diagnosis (CAD) for liver CT. Recently, interactive segmentation plays an important role in liver segmentation. In this paper we propose a fast hybrid method for liver segmentation from abdominal CT image. Firstly, the CT image is enhanced and denoised by linear stretch...
Document Script Identification (DSI) is a very useful application in document processing. This paper presents a method for this application that uses a new noise tolerant feature, the Downgraded Pixel Density feature. Compared to other features widely used in existing DSI solutions, this new feature is much more robust to variations in slant, font and style of printed documents. Experimental results...
In this paper, a new action feature descriptor PEM (PCRM-EOH-MOH) is proposed for fast human action recognition. This descriptor is constructed based on three information channels: Pixel Change Ratio Map (PCRM), Edge Orientation Histogram (EOH) and Motion Orientation Histogram (MOH) features. A video sequence is first represented as a collection of PEM features. Then, video representations are constructed...
With the development of communication, digital video compression technology turns into one of the most flourishing realm. In this paper the author introduces an AVS decoder design based on a multimedia chip-platform. In order to obtain the optimal performance, the structure of decoder adopts parallel algorithm with the centre processer and the coprocessor. The performance of the decoder which is about...
This paper studied a new method of signature identification. First, the center of image of signature has to be found. This center is regarded as the center of a circle. The radius of circle is the greatest length from the center to the edge of signature. The radius is divided into 10 equal-length parts. According to 10 different radiuses, the signature image is segmented into 10 sections by 10 equal-interval...
This paper proposed a new method of handwritten Chinese character recognition. The character image is segmented into 10 sections by 10 equal-interval concentric circles. 4 segmentation modes can be formed with the combination of 10 different-radius circles. The pixel distribution probability of strokes of character in every section is calculated. The concentric circles segmentation is an ideal method...
This paper studied a new method of seal identification. First, the image of seal is segmented into 9 equal-area quadrate sections respectively on three modes-gridding, horizontal bar and vertical bar. The pixel distribution probability of strokes in every section is calculated. It is the ratio of the pixels of strokes of every section to the pixels of seal and represents the structural and statistic...
Printing press identification can be realized with comparison between the same printed characters by different printing presses. This paper proposed a new method of printing press identification. It takes advantage of the method of Casey and Nagy and overcomes the disadvantage of the traditional the method of character recognition. In this method, the pixel distribution probability of character image...
This paper analyzed the disadvantage of the character recognition method of Casey and Nagy. It adopted advantage of two methods and proposed a new method of character recognition. In this method, the pixel distribution probability of character image is the basal index. The minimal distance product and the maximal fuzzy correlation measure are the evaluation index. It not only overcame the shortcoming...
