[0026] In order to better illustrate the purpose, concrete steps and characteristics of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings:
[0027] refer to figure 1 , a kind of space pyramid object recognition method based on kernel function matching that the present invention proposes, mainly comprises the following steps:
[0028] Step 1. Collect sample images of objects to be identified, and divide the collected sample image data into training samples and test samples;
[0029] Step 2: Convert the images of the training samples and test samples into grayscale images, and convert the data type of the grayscale images into double-precision floating point types; then scale the size of the image so that its height and width are in [50,200 ]between;
[0030] Step 3, extracting the ED-SIFT (EfficientDenseScale-invariantFeatureTransform) descriptor of the training sample and the test sample;
