Visual Positioning and Recognition of Gangues Based on ...

Received: 18 January 2019 Accepted: 20 March 2019 The coals and gangues in a raw coal image have similar visual features, due to the presence of coal ash on the surface. Thus, it is difficult to locate and recognize coals and gangues on the transmission line through visual recognition. To solve the problem, this paper proposes a visual positioning and recognition method for gangues based on ...

Detection of Magnesite and Associated Gangue Minerals ...

This study introduced a detection method for magnesite and associated gangue minerals, including dolomite, calcite, and talc, based on mineralogical, chemical, and hyperspectral analyses using hand samples from thirteen different source locations and Specim hyperspectral short wave infrared (SWIR) hyperspectral images. Band ratio methods and logistic regression models were developed based on ...

Fine-grained object detection method using attention ...

Fine-grained image recognition is an active field at present. Fine-grained object detection, an extension of fine-grained image recognition, is more significant for industrial application .It is difficult for general detector to accurately locate and classify fine-grained industrial object, because the feature reusing operation in it amplifies the conflict between “classification” and ...
