Space-time joint anomaly detection method based on hyperspectral image and electronic device

Abstract

The present invention discloses a space-time joint anomaly detection method based on a hyperspectral image and an electronic device, the method comprising: acquiring the space anomaly map of each frame of image in a hyperspectral image sequence; acquiring the time anomaly map of each frame of image in the hyperspectral image sequence; acquiring a trajectory prediction map of the target detection of a current frame according to the joint anomaly map of a previous frame of image, wherein the previous frame is a frame adjacent to the current frame; according to the space anomaly map, the time anomaly map, and the trajectory prediction map of each frame, acquiring the joint anomaly map of a target in a hyperspectral image cube. The method has a low false alarm rate and a high detection probability in aerial aircraft target detection.

Description

technical field [0001] The invention belongs to image recognition technology, in particular to a hyperspectral image-based space-time joint anomaly detection method and electronic equipment. Background technique [0002] With the development of hyperspectral sensors, hyperspectral images have been applied to many classic image processing problems. Compared with single-band sensors, hyperspectral sensors can simultaneously collect spectral feature information and spatial feature information of images. This is also an important advantage of hyperspectral images in the field of image processing. [0003] Weak and small targets refer to targets of interest that are small in size, weak in intensity, and low in signal-to-noise ratio in the image. Weak and small object detection has a wide range of applications in both military and civilian fields, and has attracted the interest of many researchers. Due to the complex background, interference of noise clutter and attenuation of ...
