A method for calculating a crowd density map in a video image sequentially includes the following steps that (101) angular points in a detection area are obtained by means of a Harris algorithm; (102) density diffusion is carried out on each angular point, and a density diffusion value of ...
Before calculating PSNR, mean square error (MSE) is calculated [64]. To be specific, H and W are used to denote the size of the video frame. The variable K(i,j) represents the pixel with embedded secret message, while I(i,j) denotes the pixel without embedded secret message. Table...

We consider different scenarios where one, three and seven consecutive frames are removed from the image sequence, although the seven-frame error suggests that it is not advisable to reduce so drastically the image density along the milling direction. A simple visual comparison offers a qualitative ...
PURPOSE: To improve the efficiency of a device by analyzing an array of picture elements with a processor combined with an image handier, determining the directivity of a test piece and a test pad, measuring the pad at a pertinent time, and calculating the result of a test. CONSTITUTION: An...
Along with that crowd behavior analysis, people count, crowd density estimation, person re identification, crowd evacuation, and forensic analysis on crowd disaster and computations on crowd analysis. A brief summary about benchmarked datasets are also given. Fast Face Detection in Violent Video ...
Evaluation: The performance of VIS is measured by first calculating the average accuracy (APAP) and the average recall (ARAR) on each class, and then averaging over the categories. APAP is the area under the precision-recall (PRPR) curve, averaged over multiple intersection-over-union (IoU) ...
The bandwidth requirements will change with the video and camera resolution and frame rate, and you should size storage accordingly. In calculating the storage space requirements, you need to consider the use of Cisco HyperFlex deduplication and the replication fac...
