In order to realize the secure transmission of the H.264 compressed video bitstream, a detailed analysis of the structure for video bitstream is performed. The parameter set and frame header data related to video decoding are retained, and the slice data payload in the network abstraction layer unit is selected as the encryption object. The video format is compliant under the premise of real time and security. The novel cross-coupled chaotic system is designed as the key stream generation compon...

Human activity recognition (HAR) is an important branch of human-centered research. Advances in wearable and unobtrusive technologies offer many opportunities for HAR. While much progress has been made in HAR using wearable technology, it still remains a challenging task using unobtrusive (non-wearable) sensors. This paper investigates detection and tracking of multi-occupant HAR in a smart-home environment, using a novel low-resolution Thermal Vision Sensor (TVS). Specifically, the research pre...

Recognition of micro-expressions depends on the key features provided in the form of the temporal information. It needs considerable effort, however, to manually design useful characteristics. Subtle or micro-facial expressions are much difficult than regular facial expressions rich in emotional expressions in a true environment to be identified. An easy solution is discussed in this paper to recognise facial micro-expressions that utilizes an algorithm mix for facial identification, feature ext...
