Fast Moving Object Recognition


The Brain-Like Artificial Intelligence (BLAI) is pioneered by Prof.Nikola Kasabov and here it is applied to a specific application.

Moving object recognition is a challenging problem in computational intelligence. Fast moving object is considered as the one which could not easily be captured by conventional cameras in real time. The typical examples encompass fast moving cars, flying rockets, bouncing ping-pong balls, tennis balls, balancing pencils etc. It is impossible to recognize such moving objects without using a suitable algorithm and effective software system which are capable to learn and recognize patterns from complex Spatio- and Spectro-Temporal Data (SSTD). Deep learning has improved machine learning in computer vision from end to end. In this paper, we propose a new methodology for deep learning of video data and for accurate classification of moving objects captured in the data using eSNN (evolving Spike Neural Network). Taking video footage encapsulating moving objects as input data, we conduct convolution operations for each video frame by using a Gaussian filter as the first step of deep learning, then adaptive down sampling is used to shrink the video frame both in width and height, after that spike encoding of these features is applied over time to identify the changes of each image block. Finally, we use the spikes of each 10 ×10 block of video frames as features and import them into NeuCube for training and testing using dynamic evolving spiking neural network as a classifier to classify movement of the objects. Compared to other deep neural networks and other machine learning techniques, our NeuCube model has outperformed in various scenes for fast moving object recognition using spatio- and spectro- temporal video data, achieving accuracy of about 90%. It can be used for both high and low-resolution videos. Moreover, it allows to be further trained on new data in an on-line and incremental mode.

The proposed methods and systems, when compared with traditional statistical and machine learning methods, showed superior results in the following aspects:

  1. Better data analysis and classification/regression accuracy (by 10 to 40%);
  2. Better visualisation of the created models, with a possible use of VR;
  3. Better understanding of the data and the processes that are measured;
  4. Enabling new information and knowledge discovery through meaningful interpretation of the models.
