Embodiment Construction
[0083] The method, device, and storage medium for determining an image boundary provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0084] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations.
[0085] The terms "first" and "second" in the specification and drawings of the present application are used to distinguish different objects, or to distinguish different processes for the same object, rather than to describe a specific sequence of objects.
[0086] In addition, the terms "including" and "having" mentioned in the description of the present application and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, prod...

The invention discloses an image boundary determination method and device and a storage medium, relates to the technical field of image processing, and can detect the boundary of an earthwork material pile image. The method comprises the following steps: dividing image blocks of a target image, extracting image texture features of the image blocks, determining block classification results of the image blocks according to the image texture features, and determining a block classification matrix according to the block classification results; classifying the target image to obtain a classification result corresponding to the target image; according to a classification result corresponding to the target image, performing convolution processing on the block classification matrix based on a compensation convolution kernel and a filtering convolution kernel to obtain a compensation filtering matrix; and determining at least one boundary of the target image based on elements in the compensation filtering matrix. The compensation filtering matrix is used for correcting elements in the block classification matrix; elements in the block classification matrix represent block classification results of the image blocks at the corresponding positions.
Description
technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to a method, device, and storage medium for determining an image boundary. Background technique [0002] At present, when determining the image boundary, the boundary detection method based on image features, the boundary detection method based on the model or the boundary detection method based on deep learning are often used, and the boundary of the image to be detected can be determined by the above methods. [0003] However, for images of earthwork material piles under complex working conditions, due to the large number of material types and the close coloring of materials, the above method cannot accurately fit the boundaries of earthwork material pile images, that is, using the existing boundary detection The method cannot accurately determine the boundary of the image of the excavated stonework material pile. Therefore, it is urgent ...
