Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the 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.

[0056] A robot scene recognition method based on a scale-invariant feature extreme learning machine, comprising the following steps:

[0057] Step 1, in the embodiment, the images are used to randomly select 500 pictures from the ImageCLEF library. 450 of them are used as training samples and 50 are used as testing samples. We first enhance and normalize the image to obtain a standardized image with the same size and the same gray value.

[0058] Step 2: Scale-invariant feature conversion is performed on the training images, and the scale-invariant features of all training images are combined to form a new matrix set. Th...

Abstract

The invention discloses a scale-invariant feature extreme learning machine-based robot scene recognition method. The method comprises the following steps: firstly, expressing a scene of a robot visual image by using a scale-invariant feature; secondly, realizing a robot scene image expression codebook by using a K mean clustering algorithm; finally, establishing mapping relation between the robot visual scene image and a scene label by using the extreme learning machine algorithm. According to the method, the complexity of parameter estimation and optimization of a conventional neural network is reduced, the training time is further shortened and the recognition rate of the robot scene image is improved by using the advantages of the extreme learning machine.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a robot scene recognition method based on a scale-invariant feature extreme learning machine. Background technique [0002] Vision is the most intuitive and effective way for humans to observe and understand the world. Robot vision simulates the function of human vision to perceive and recognize the outside world from one or more images. As an important part of the field of robot vision, the recognition of scenes in images has been the focus of many researchers. In recent years, robot scene recognition technology has been widely used in criminal investigation systems of public security departments, medical image processing, 3D modeling, industrial inspection and other fields. [0003] The robot scene recognition application technology is to give an input scene image and recognize its registered scene category information. After the scene image is obtained by electroni...
