Real-Time Automatic Object Classification and Tracking using Genetic Programming and NVIDIA R CUDA TM

Genetic Programming (GP) is a widely used methodology for solving various computational problems. GP's problem solving ability is usually hindered by its long execution times. In this thesis, GP is applied toward real-time computer vision. In particular, object classification and tracking using a parallel GP system is discussed. First, a study of suitable GP languages for object classification is presented. Two main GP approaches for visual pattern classification, namely the block-classifiers and the pixel-classifiers, were studied. Results showed that the pixel-classifiers generally performed better. Using these results, a suitable language was selected for the real-time implementation. Synthetic video data was used in the experiments. The goal of the experiments was to evolve a unique classifier for each texture pattern that existed in the video. The experiments revealed that the system was capable of correctly tracking the textures in the video. The performance of the system was on-par with real-time requirements.

HG 34.70-34.85

Dark brown sediment with clasts that range from small to medium in size. The clasts were sub-angular to sub-rounded in shape. Lineations were abundant throughout the sample. It also contains some clay material and a few rotation structures.

GAO 34

Brown sediment with clasts ranging from small to large in a sandy matrix. Clast shape ranges from angular to rounded. The clasts are mainly well dispersed. Rotation structures are common in this sample, along with grain crushing. Some lineations can also be seen in this sample.
