04/28/2006 Project launching meeting (Dr. Tasi, Dr. Wang, Pilho -- namly All members): Discuss the topic of the project (MUTCD) for Pilho's summer RA.
05/04/2006 Regular meeting (all): The objective of this meeting is to discuss with the preliminary thought that Pilho have on developing the NN and Dr. Wang will provide Pilho with the input ROIs.Continue reviews on existing approaches. Manually select tens of warning sign candidates from MUTCD databases. Find proper image abstractions or features for neural network training.
05/12/2006 Regular meeting (all): We watched the traffic warning class signs together and discussed the next approaches to be composed in a number of steps. Dr. Wang suggested to make a system be modularized so that a neural network specifically for the recognition part (expected outputs namly W-1, W-2, etc.) to be independable in the view of implementation to priori systems like feature extractors including correlation computing modules or OCR. In summary, a neural network recognition module should use the features extracted by heterogeneous computing modules that extract ROI and associated features from a raw image in a unified way to classify the input into one of predefined categories.
05/17/2006 Regular meeting (all): Extensive discussions were done on the proper features to extract from the traffic sign raw images. In addition, the proper neural architecture in which number of dimensions is also talked about. In conclusion, we set the next intermediate goal as testing the performance of line receptors as image abstraction features and plus finding a proper ANN engine for our experiment.
05/25/2006 Regular meeting (all): Discussion on the on-going project that measures the location of buoys on the Savannah port. ANN engine tests were reported and FANN is selected as our preliminary ANN engine. We will keep extending ANN training experiment for the real traffic sign cases and future enhancing its recognition performance.
