This paper proposes a new dynamic neural modelling method for mechatronic system prognostics. A simulated turbofan engine system is firstly introduced. Then, so-called health index (HI) for the system is evaluated by an artificial neural network model called extreme learning machine (ELM) to recognize the health conditions. In order to track and predict the propagation process of the system based...
This study presents an automatic, human perception based chroma-keying algorithm that extracts the objects of interest (i.e. foreground) from monochromatic background. Given an image to be chroma keyed, the global colour distribution and the local texture property are analysed in CIECAM02 colour appearance model. After the analysis, input image is automatically segmented into three parts: foreground,...
