Application: Evaluation method (Patent ID: US20240104908A1)

The patent filed by Canon Inc. describes an evaluation method for an image analysis system that involves inputting an evaluation image to the system, comparing the output value with an expected value to determine accuracy, and evaluating the system's characteristics based on the relationship between a factor and the output accuracy. The method includes generating multiple evaluation images and expected values based on the factor, with the output value being binary and the accuracy measured using an Area Under Curve (AUC) of a Precision-Recall (PR) curve.

Furthermore, the evaluation method considers external environmental factors such as illuminance, color of illumination, saturation, contrast, brightness, sharpness, white balance, noise, and compression ratio of the evaluation image, as well as internal processing factors. The setting value range indicating ease of setting is determined based on the relation between the setting value of the image analysis system and the accuracy of the output, with the range of setting values that are actually effective being identified. Additionally, differentiating processing based on past frames or input images is performed, with the internal processing factor being a setting value related to this differentiation or the characteristics of analysis processing based on external environmental factors.
