Embodiment Construction
[0034] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.
[0035] The present invention proposes a ground-based visible light cloud image classification method based on a bag-of-words model and an extreme learning machine. The extreme learning machine model obtains a cloud image classifier, and identifies any ground-based visible light cloud image as a certain type of cloud. In this embodiment, the cloud map types are set to four, including cumulus clouds, cirrus clouds, stratiform clouds, and clear sky.
[0036] refer to figure 1 , the implementation steps of the present invention are as follows:
[0037] Step 1: Perform image preprocessing on the ground-based visible light cloud image to obtain a standard cloud image, and randomly classify the standard cloud image to obtain training samples and test samples.
[0038]Set an image size threshold T, and process 4 types of ground-based visible light...
