Noise and non-uniform gray level in underwater image cause the low segment precision, this paper presents a segmentation framework based on morphological component analysis (MCA) and fuzzy clustering with variational level set. The framework uses MCA method to sparse decompose the image into texture and cartoon parts. The cartoon part contains the mainly information with less noise, which is good...
Underwater image contains a lot of noise and non uniform gray levels. That characteristic causes the image has a low segmentation precision. A segmentation method based on morphological component analysis (MCA) and adaptive level set evolution is proposed in this paper to enhance the precision. MCA method is used to sparse decompose the image into texture and cartoon parts. The cartoon part contains...
Although the direct combustion of biomass for energy that applies circulating fluidized bed (CFB) technology is steadily expanding worldwide, only few studies have conducted an environmental assessment of biomass ash thus far. Therefore, this study aims to integrate information on the environmental effects of biomass ash. We investigated the concentration of heavy metal in biomass ash samples (bottom...
The rheological characteristics of granular pseudo-fluid are studied using conventional method from continuous-flow theory. Quartz sand particle systems in different sizes, spherical glass particles and alumina particles are focused in this work for their low-velocity shearing movements in a small gap between two concentric rotating cylinders. The accurate rheological equations of those granular systems...
A computer-aided assessment method of man-machine interface(MMI) for display and control centers(DCC) in the power plants was proposed. The digital Chinese human body model(HBM) for assessment was developed based on UG/OPEN API; the design-related ergonomics standards of DCC were studied, and the quantitive objective indexes are used as the assessment indexes; the quantifying methods of assessment...
