Image inputting and coupling unit
TLDR
In this paper, a pre-processing circuit was used to enhance reliability of a function evaluation test regarding the preprocessing of input data by incorporating a function generating a test image data.Abstract:
PURPOSE:To enhance reliability of a function evaluation test regarding the pre-processing of input data by incorporating a function generating a test image data CONSTITUTION:The titled unit is provided with a pre-processing circuit 1 which applies the prescribed pre-processing to image data that an image reader has read out and inputs it to an image memory, and a test image generator circuit 2 generating test image data for inputting the pre-processing circuit 1 The built-in test image generator circuit 2 generates test data, which the pre- processing circuit 1 employs to conduct a performance evaluation test Thus the variance of the test image data is eliminated to enhance the reliability of test resultsread more

Test system of recognition processor
TL;DR: In this paper, the problem of discriminating the normalness of the recognizing function of a recognizer with a small amount of test data was addressed by transmitting a picture signal to a recognition processor and collating the result of the recognition processing with the correct answer data.
