This paper presents the design and implementation of a new recognition method to monitor home accident and anomalies based on home environmental voice. Gaussian Mixture Models theory is utilized to modeling and identifies home environmental situations, so that it can perform real time detection and recognition for solitaries. The whole process includes four steps: pretreatment of voice signal, extracting...
In order to realize accurate detection of moving human in complex and cluttered scene and eliminate the influences of moving shadow, an adaptive moving human detection algorithm based on Gaussian mixture model is presented. This algorithm employs Gaussian mixture distribution in modeling background of each pixel and an on-line approximation to update the model. The moving human region is detected...
