Embodiment 1

[0041] figure 1 is a flow chart showing the object feature extraction method according to Embodiment 1 of the present invention.

[0042] refer to figure 1 , in step S110, acquire feature data of multiple scales of the target object from the image to be checked.

[0043] Here, the image to be checked may be a static image or a video frame image containing the target object. The target objects may be objects with visible shapes such as pedestrians, vehicles, animals, and flying objects.

[0044] Feature data of multiple scales of the target object can be extracted from the image to be checked by an applicable image processing method. Here, multiple scales can be understood as multiple scale resolutions, and the feature data of any scale can be, for example, the texture feature data of the image, the color feature data of the image, the shape feature data of the object, or, from another perspective, for the The feature vector matrix of the scale-extracted image, etc.

Embodiment 2

[0052] figure 2 It is a flow chart showing the object feature extraction method according to the second embodiment of the present invention.

[0053] For ease of description, in the present disclosure, it is assumed that the aforementioned multiple scales are N scales, and N is an integer greater than 1.

[0054] In addition, according to this embodiment, feature data of any scale includes a first feature map corresponding to multiple feature channels of that scale. Here, the plurality of feature channels may correspond to a plurality of predetermined image features or object features, so as to characterize the response degree of the image to the image features or object features corresponding to each feature channel.

[0055] refer to figure 2 , in step S210, the first feature maps of N scales of the target object are acquired from the image to be checked.

[0056] For example, multiple convolutions and multiple downsampling pooling are performed on the image to be inspe...

Embodiment 3

[0080] image 3 It is a flow chart showing the object feature extraction method according to the third embodiment of the present invention.

[0081] In the method for extracting object features in Embodiment 3 of the present invention, the first neural network for generating fused feature data and / or the second neural network for feature extraction may be used to perform the corresponding steps.

[0082] refer to image 3 , in step S310, acquire feature data of multiple scales of the target object from the image to be checked through the second neural network.

[0083] Specifically, the feature data of multiple scales of the target object can be obtained from the image to be checked through the pre-trained second neural network. The second neural network can obtain multi-scale feature data of the target object by performing multiple convolutions and pooling on the image to be checked.

[0084] As mentioned above, optionally, the feature data of any scale includes the first ...

Abstract

The embodiment of the invention provides an object characteristic processing method, an object characteristic processing device, a storage medium and electronic equipment. An object characteristic extraction method comprises the steps of acquiring characteristic data of multi-scales of a target object from a to-be-detected image; generating respective attention heat data of each scale according tothe characteristic data of each scale, wherein the attention heat data represent attention heat of each attention part region of the target object; and acquiring fusion characteristic data of the target object according to the characteristic data of each scale and the attention heat data of each scale. Therefore, the fusion characteristic data fused with the characteristic data of details and overall semantics and the attention heat data are obtained, thereby being beneficial to subsequently and accurately completing an image processing task based on the fusion characteristic data.

Description

technical field [0001] Embodiments of the present invention relate to artificial intelligence technology, and in particular to an object feature processing method, device, computer-readable storage medium, and electronic equipment. Background technique [0002] For solutions such as object attribute detection tasks, object recognition tasks, etc., global features are usually extracted directly from images, and corresponding tasks are completed according to the extracted global features. Since the global feature represents the high-level semantic features of the image, detailed information in the image that is very useful for completing the aforementioned tasks may be lost, such as clothing stripes, whether to wear glasses, etc., thus affecting the accuracy of the aforementioned tasks. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an object feature extraction technology. [0004] According to the first aspect of an...
