Camshift algorithm has the advantage of better real-time, but this algorithm is only suitable for tracking targets in simple cases, not well for tracking desired targets in complex situation. In this paper, we will present an improved method of multiple targets tracking algorithm based on the Camshift algorithm combined with Kalman filter. The tracker of the improved method was used to track each detected target. It can achieve tracking of multiple targets. A large number of experiments have proved that this algorithm has strong target recognition ability, good anti-noise performance, and fast-tracking speed.</p> Md Shaiful Islam Babu Copyright (c) 2019 Advances in Image and Video Processing Sun, 08 Sep 2019 08:22:55 +0000 Encrypted Color Image Transmission in LQ-based GSIC Pre-coded Multiuser Downlink Wireless Communication System <p>The use of LQ-Based GSIC pre-coding scheme in next generation cellular mobile network can be a robust and effective technique for unique cancellation of multiuser interference. In 5G/beyond 5G a great emphasis is being given on ensuring physical layer security. In this paper, an investigative study has been made on the performance evaluation of encrypted color image transmission in LQ-based GSIC pre-coded multiuser downlink wireless communication system. The 6×2 multi-antenna configured simulated system under investigation incorporates SPC (3, 2) channel coding, low order digital modulations (QAM, QPSK, DQPSK), DNA and sine map based RGB image encryption and Zero Forcing (ZF) signal detection techniques. In the scenario of encrypted multiuser color image transmission over AWGN and Rayleigh fading channels, it is observable that the simulative system is very much effective and robust in retrieving color image for each of the three users under a moderate signal to noise ratio of 10 dB.</p> MD OMOR FARUK, Shaikh Enayet Ullah Copyright (c) 2019 Advances in Image and Video Processing Sun, 08 Sep 2019 08:21:36 +0000 A Framework: Region-Frame-Attention-Compact Bilinear Pooling Layer Based S2VT For Video Description <p>In the video description task, the temporal information and visual information of the video are very important for video understanding, and high-level semantic information contained in mixed features of text features and video features plays an important role in the generation of video caption.In order to generate accurate and appropriate video captions.Based on the S2VT (sequence to sequence: video to text)framework, we propose a video description neural network framework (RFAC-S2VT) with a two-level attention and compact linear pooling layer (CBP) fusion.We use visual information and category information from the dataset for class training, and then we use CNN to extract the trained visual features.In the encodering stage,this paper designs a regional attention mechanism to dynamically focus on each frame of video,and then the region-weighted 2D visual features and C3D visual features containing temporal information are then fused together. We use the characteristic of model to model the fusion visual features with temporal information.In the decodering stage, this paper designs a frame-level attention ,and then fine-grained the video features which has been focusd by frame-level attention and the text features in the dataset by using compact linear pooling layer (CBP),finally model generated relevant video caption.We validate the proposed network framework on the MSR-VTT dataset,the results show that our proposed neural network framework is competitive on this dataset and current state of the art.</p> Haifeng Sang Copyright (c) 2019 Advances in Image and Video Processing Sun, 08 Sep 2019 08:24:15 +0000
