LGC Dataset

This is an uncooled LWIR dataset named LGC. It was captured utilizing the IRay Tech LGC6122 uncooled infrared core, a device also employed inpractical applications. A significant advantage of our dataset lies in the 72 mm focal length of the LGC6122, which facilitates the detection of human subjects at distances of up to 1.3 kilometers and vehicles at distances of 1.7 kilometers. In contrast, the FLIR dataset features a focal length of 13 mm, while the KAIST dataset has a focal length of 7.5 mm. The LGC6122 operates at a standard resolution of 640 × 512 pixels and functions withinthe 8–12 μm wavelength range, characteristic of typical LWIR detectors. The infrared images included in our dataset were captured at Kunming Pool Qixi Park in Xi’an, Shaanxi, China. Data collection occurred during nighttime and afternoon hours in both spring and winter seasons. The scenes represented in our dataset encompass buildings, lakes, and trees observed from considerable distances, thereby offering a diverse array of challenging scenarios for infrared image enhancement. Given the labor-intensive process of identifying appropriate locations for long-distance target detection, our dataset comprises a total of 668 images.
