Features Extracting of Sinter Ores Photomicrograph Based on Calculating Model of Reflection Index and Peak-find Model of Gray Histogram
The intelligent recognizing and processing system for sinter ore mineragraphy make a great convenience of recognition and measurement.Specially,its critical important for a successful intelligent system to extract the minerals feature accurately and sufficiently.Reflection index,as the crucial feature of mineral,is calculated by the theoretical calculating model of index based on the principle of imaging color models.In gray histogram of minerals micrograph,the peaks positions represent the information about mineral categories and contents.The relationships of different mineralspeak-positions in curve of gray histogram were got by using the peak-find model of gray histogram and calculating model of reflection index.These two models which can be regard as the method of feature extraction for minerals photomicrograph also lay a good foundation for the artificial intelligent system of recognition and processing in sinter ore.
