Embodiment Construction
[0021] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.
[0022] like Figure 1 to Figure 4 As shown, a millimeter-wave imaging image processing method includes the following steps: S1 collects images through a millimeter-wave imaging system, S2 performs noise reduction processing on the collected images, S3 divides the noise-reduced image into multiple sub-images, S4 extracts the two-dimensional spectrum of each sub-image, S5 extracts feature vectors of the two-dimensional spectrum of the sub-image, and S6 classifies the extracted feature vectors.
[0023] For step S1 to acquire images through the millimeter wave imaging system:
[0024] Using the millimeter wave imaging system to collect a large number of human target images, such as figure 1 shown.
[0025] For step S2, noise reduction processing is performed on the collected image:
[0026] In order to achieve good results in subsequent ...
