The Dead Sea Scrolls were discovered in the Qumran area and elsewhere in the Judean desert beginning in 1947 and were photographed in infrared in the 1950s. Recently, the Israel Antiquities Authority embarked on an ambitious project to digitize all the fragments using multi-spectral cameras. We describe a method that utilizes information from both of these image sets: the highly detailed multispectral...
In this paper, we propose an efficient scene text localization method using gradient local correlation, which can characterize the density of pair wise edges and stroke width consistency to get a text confidence map. Gradient local correlation is insensitive to the gradient direction and robust to noise, small character size and shadow. Based on the text confidence map, the regions with high confidence...
In this paper, we construct a word association network from DBLP bibliography records and detect its evolution progress based on community discovery algorithm CPM and CPMw. We found that the network is of complex network characteristics, and the detected semantic communities can be classified into two categories: giant community and small community. They differ in size and content, and behave differently...
Texts presented in video can provide important semantic information. In this paper, we propose an algorithm to detect texts from news videos. First, SPAC (spatial autocorrelation method) is used to determine the degree of texture rough-detail of video frames and determine candidate text regions based on texture rough-detail. Then Sobel operator is used to extract edges of candidate text regions, and...
Postal automation is yet a partially solved challenge, and part of the challenge is the automatic and accurate extraction of stamps in envelope. We observed that the stamp perforations form a distinct boundary between the stamps and the background. The number and the linear distribution of stamp perforations can be utilized to extract and validate each stamp accurately. In this paper we approach this...
