Embodiment Construction

[0059] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0060] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0061] The advent of the era of high-spatial-resolution earth observation has led to an explosive growth of remote sensing data. However, compared with the volume of remote sensing data that has been acquired so far, ...

Abstract

The invention discloses an image retrieval and classification method and system, a terminal and a storage medium. The method comprises the steps of obtaining a to-be-queried image; inputting the to-be-queried image into a target Hash classification network to obtain a predicted Hash code and a predicted image category corresponding to the to-be-queried image; and obtaining a target database Hash code, and determining a target image set corresponding to the to-be-queried image according to the target database Hash code and the prediction Hash code. The image category of the to-be-queried image and a group of similar images corresponding to the to-be-queried image are determined in a Hash code mode, the problem that the scene category of an image cannot be obtained by an existing image retrieval method based on content is solved, and further analysis and processing of the image are facilitated.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image retrieval and classification method, system, terminal and storage medium. Background technique [0002] The advent of the era of high-spatial-resolution earth observation has led to an explosive growth of remote sensing data. However, compared with the volume of remote sensing data that has been acquired so far, the utilization rate of remote sensing images is still far below people's expectations. In the face of massive and complex remote sensing images, how to more effectively search for scenes of interest to users from existing databases is the basis for subsequent interpretation and application of remote sensing images. question. [0003] For remote sensing image retrieval, the challenge lies in how to design a retrieval system to return samples similar to the query image in an accurate and efficient manner. Early retrieval methods mainly exploited manually annotate...
