Frequency-Enhanced and Multi-Scale Feature Fusion YOLOv11 for Low-Illumination Weak Projectile Target Recognition in Linear Array CCD Sensor
To solve the problem where the low contrast and extremely small target size in the three-sky-screen target-integrated linear array CCD sensor measurement system under low-illumination conditions make it difficult to accurately identify projectile targets, this paper proposes a method of Frequency-Enhanced and Multi-sca...
