Title: Hyperspectral image classification method and apparatus, electronic device and storage medium
Inventor: LI YANSHAN
IPC: G06N3/04
Filed: 2021-12-16
Abstract: A hyperspectral image classification method and apparatus, an electronic device and a storage medium. The method comprises: establishing a corresponding third-order local spatial spectral tensor by means of extracted image elements of a hyperspectral image (101); using a class tensor decomposition algorithm to decompose the third-order local spatial spectral tensor so as to obtain an image element spectral component and an image element spatial component (102); using a convolutional network to separately convolve the image element spectral component and the image element spatial component so as to extract a corresponding spectral feature vector and spatial feature vector, and concatenating the spectral feature vector and the spatial feature vector to obtain a spatial spectral feature of the hyperspectral image (103); and classifying the hyperspectral image on the basis of the spatial spectral feature (104). By means of the described method, a class tensor decomposition algorithm is used to analyze features of a hyperspectral image in spatial and spectral dimensions, which effectively removes redundant information present in image elements of the hyperspectral image and improves the efficiency of the subsequent extraction of spatial spectral features, thereby improving the classification accuracy of hyperspectral images.

Abstract: A fault image generation method and apparatus. The fault image generation method comprises: acquiring a non-fault image and a first fault image, wherein the non-fault image records a first object, in which no fault occurs, the first fault image records a second object, in which a fault occurs, and the type of the first object is different from that of the second object; and migrating a fault pattern of the second object in the first fault image onto the first object in the non-fault image, so as to obtain a second fault image, wherein the second fault image presents the first object in a fault state. A partial image of a certain type of object is replaced with a fault pattern, which records another type of object, so as to obtain a second fault image of the certain type of object, thereby improving the universality and the flexibility of acquiring the fault pattern, and increasing the diversity of fault types in the second fault image.

Abstract: The present application provides a metasurface optical element, a design method and a structured light projection module, which relate to the technical field of optics. The metasurface optical element comprises: a substrate and a plurality of nanometer antennas which are provided on the substrate and which modulate incident beams by means of transmission phases. The size of at least two nanometer antennas are different, and the plurality of nanometer antennas are distributed in an array on the substrate. The distance between the centers of two adjacent nanometer antennas is the same, and the transmission phase of each nanometer antenna is the superimposition of a collimation phase and a diffraction phase. Therefore, the formed metasurface optical element may have collimation and diffraction functions at the same time, that is, a collimation element and a diffraction element are integrated. Space occupied by existing collimation and diffraction elements as two independent optical elements is effectively reduced; meanwhile, since the alignment assembly of the collimation element and diffraction element is omitted, alignment error caused by the alignment assembly may thus be effectively reduced.
