rate. At last the designed CNN are trained and tested. The trained CNN can be combined with a sliding window technique to detect any ROI with size larger than 256×256 resolutions in the original images. The experimental results show that the defect detection rate of the designed CNN can ...
During the production of metal material, various complex defects may come into being on the surface, together with large amount of background texture information, causing false or missing detection in the process of small defect detection. To resolve those problems, this paper introduces a new mode...
The capacitor charging time constant is selected so that the threshold is reached if the recurrence rate of the multivibrator output pulses falls below a reference rate less than twice the lowest intended picture carrier frequency, whereby gate switching indicates the presence of input signal ...
YOLOv5-CD: Strip steel surface defect detection method based on coordinate attention and a decoupled head head detector. By separating the classification and regression tasks, this approach effectively increases the model's detection precision and convergence rate. ... B Wang,M Wang,J Yang,... ...
How Can Computer Vision Help with Defect Detection? With computer vision, you can detect any defects visible to a camera. When a defect is detected, you can trigger automated systems such as removal of a product from an assembly line. Or, if defect rate reaches a defined incidence level, ...
