    Abstract: In order to achieve effective protection of color image information, an encryption algorithm with the combination of pixel scrambling and ciphertext crossdiffusion technology is proposed. Firstly, the chaotic sequences generated by three fractionalorder chaotic systems are modified to obtain two groups of chaotic key sequences with good property, and the RGB color image is converted into a grayscale image which is composed by primary color components. Secondly, the pixels’ positions of the grayscale image are scrambled by means of one group of improved chaotic key sequences. Thirdly, by using another group of improved chaotic key sequences, the study modifies the pixels’ values of the scrambled image with two rounds of ciphertext crossdiffusion operations between the primary color components and gets the cipher image. Simulation shows that, this algorithm is of a sufficiently large key space, highly sensitive keys, better pixel distribution characteristics, and a good performance against ciphertextonly attack, differential attack, chosen plaintext attack and statistical attack. This can be widely used in secure communication of multimedia data.

    Abstract: Aiming at making an improvement on the information capacity of video summary under the premise of summary speed, a new method for video summarization based on rotation invariant uniform pattern feather is presented in this paper. First of all, the amount of frames to be processed is decreased with the presampling approach, upon which local binary pattern feature is extracted. Then, the cluster number is generated according to the similarity between each two adjacent frames. With the cluster number, the kmeans algorithm is applied to cluster similar frames. Finally, the frame which is nearest to the cluster center is used to construct the video summarization. The importance of cluster is evaluated by the function introduced. Experiment results indicate that the proposed method can making an improvement on the information capacity of video summary under the premise of generation speed, the summary performs well to the source video.

    Abstract: Based on the nonlocal means(NLmeans) filter algorithm, in order to improve the image quality, a NLmeans algorithm based on wavelet packet transform is proposed. Firstly, the image is transformed by the wavelet packet, and the wavelet domain coefficients are applied to estimate the Gaussian noise parameters of the image, then the similarity of the highfrequency subband’s wavelet coefficients is calculated as the weights to adjust the wavelet coefficients, finally the image is reconstructed by the inverse wavelet packet transform. Experiment results show that this algorithm can preserve the edge detail information effectively, and get a superior denoising performance than the original nonlocal mean algorithm.

    Abstract: Traditional image edge detection algorithm based on integer order differential is sensitive to noise, and the image edge detection results are often simple. The fractional differential can enhance the high frequency and keep the middle and the low frequency of the image signal. The paper infers the difference expression of the GL fractional differential, and designs a 5×5 size template. The image edge detection experiments are made with the Sobel, the Prewitt, the Laplacian, and the GL fractional differential algorithm. The results show that the fractional differential algorithm is not sensitive to noise, and can keep the image texture detail of the smoothing region and get more information of the image edge.

    Abstract: In image processing, segmentation algorithms constitute one of the main focuses of research. In this paper, new image splitandmerge segmentation algorithms based on a hard version of the information bottleneck method are presented. The objective of this method is to extract a compact representation of a variable, considered the input, with minimal loss of mutual information with respect to another variable, considered the output. First, the algorithm is based on the definition of an information channel between a set of regions (input) of the image and the intensity histogram bins (output). From this channel, the maximization of the mutual information gain is used to optimize the image partitioning. Then, the merging process of the regions obtained in the previous phase is carried out by minimizing the loss of mutual information. Different experiments on 2D images show the behavior of the proposed algorithm.

    Abstract: In most operating systems which are diskbased system, buffer management algorithm concerns only data hit ratio. However, write cost of flash memory is much more than read cost. In order to improve the performance of flash, we propose the OCFLRU algorithm which is an optimal of the CFLRU. This algorithm used a mixed pageblock data structure to manage clean pages and dirty page clusters. When buffer had no spare space, clean page was preferred to be evicted and dirty pages cluster was evicted from list at last. In this way, performance is improved by reducing writing and erasing.

    Abstract: The characteristics of passive receiving serial communication are the lower machine is always sending data to upper computer， but the upper computer receives data passively in the case of not knowing when the machine sending data. This paper studies the application of passive receiving serial communication based on LabVIEW, and designs two serial collection systems for data acquisition on the basis of the characteristics of passive receiving serial communication. Polling serial ports communication can obtain data by using the loop structure querying buffer continuously. Because of the incomplete received date at times, the system saves all the data received from upper computer to temporary files, and we can obtain data by reading the temporary files. To prevent using the loop structure querying buffers of all the serial ports continuously, which result in the waste of the system resources, triggering serial ports communication can obtain data by communicating with outside through shared variables, and trigger serial ports separately by the change value of shared variables. Only need to set some serial port parameters, the two systems can display, playback and realtime storage the data collected by hardware， and can provide convenience for the future research of the collected data. The actual experiment verifies the system is stability and reliability.

    Abstract: The article states the design and development of an automation platform based on a general underlying layer and portal integration. The underlying layer undertakes all data access for the whole system. Based on this, it establishes 3 office subsystems for the professional school: the administrative office subsystem, the student affair subsystem and the education assessment subsystem. It adopts the principle of “Enterprise Portal”(EP) to integrate 3 subsystems seamlessly, i.e. once a user signed on the system, he could access all functions which have been granted to him, and no need multiple signon.

    Abstract: Face imagebased age classification is an approach to classify face images into one of several predefined agegroups, it is a multiclass problem. For solving the multiclass problem, a SVM extension is proposed which combines the method of errorcorrecting output codes (ECOC) with binary SVM classifier. Gabor aging features are extracted to represent the face images, and the two principal components (2DPCA) are used to reduce the dimension of the extracted features. Experimental results on FGNET database are reported to demonstrate its effectiveness and robustness. The results obtained using the fused Gabor and 2DPCA features are better than the one when using 2DPCA alone.
