Images of human faces, each 256*200 in size with 64 shades of gray, are stored in a gray-level referenced file. Face matchings were performed in two stages. In the first stage, image processing techniques were used to extract six features from each of the gray-level images. Each face is represented by a vector of six dimensions and is stored in the six-feature referenced file along with the gray-level images. The same features from an unlabeled face were then extracted and a search was performed to locate the most likely candidates in the six-feature file. Computations were greatly simplified since matching was based on six numbers and many of the unlikely candidates were eliminated at this stage. The second stage involved the matching of all facial features of the unlabeled face to those of the most likely candidates in the gray-level file. Time required to match a face was greatly reduced since comparison of all facial features was done on relatively fewer most likely candidates. Experimental results indicated that with a small referenced file of ten persons the system was able to correctly classify unlabeled faces 80% of the time. Currently a computing time of 15 minutes is needed for each classification.<<ETX>>","PeriodicalId":6453,"journal":{"name":"[1991] Proceedings of the 34th Midwest Symposium on Circuits and Systems","volume":"27 1","pages":"641-644 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1991-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87691820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results obtained are related to the single-variable case, but the main conclusions can be generalized for the multidimensional case. The net is a modified perceptron with one hidden layer of sigmoidal units and two intermediate output linear units that are linearly combined to provide the final mapping. In particular, the problem concerning the starting weight configuration and the conditions that guarantee the correct learning with a random setting is analyzed. Other neural computations providing similar solutions to the approximation problem suffer from convergence to a local minimum if the starting network configuration is arbitrarily chosen, thus requiring a previous computation of the interpolating parameters that provides a weights setting quite close to the global optimum. In the present approach, one of the intermediate outputs is somewhat related to the curve derivative so that the overall net behavior can be viewed as a curve derivative integrator in which the second output is related to the constant term to be added to the undefined integral calculation. Simulation results, obtained after randomly setting the starting weight configuration, show excellent performance for all the trained functions.<<ETX>>","PeriodicalId":6453,"journal":{"name":"[1991] Proceedings of the 34th Midwest Symposium on Circuits and Systems","volume":"1 1","pages":"545-548 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1991-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82121401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
