| Summary: | Human posture recognition is gaining increasing attention in the field of computer vision due to its
promising applications in the areas of personal health care, environmental awareness, human-computerinteraction and surveillance systems. Human posture recognition in video sequences is a challenging task
which is part of the more general problem of video sequence interpretation. In this project, an intelligent
human posture recognition system using a single static camera is proposed. The project consists of two
stages: the first stage is training and evaluation and the second is deployment. In the first stage, the system
is trained and evaluated using a dataset of human postures to ‘teach’ the system to classify human
postures for any future inputs. When the training and evaluation process is deemed satisfactory as
measured by recognition rates, the trained system is then deployed to recognize human postures in any
input video sequence. In the training stage, to obtain the human posture datasets, video sequences have
been recorded and preprocessed to extract human silhouettes. The training and testing were performed
using four different classifiers which are Multilayer Perceptron Feedforward Neural networks, SelfOrganizing Maps, Fuzzy C Means and K Means. The recognition rates (accuracies) of those classifiers
were then compared and results indicate that MLP gives the highest. Performance comparisons between
the proposed systems and existing systems were also carried out. |
