This paper proposes a blur detection algorithm that is capable of detecting and quantifying the level of spatially-varying blur by integrating directional edge spread calculation, Just Noticeable Blur (JNB) and local probability summation. The proposed method generates a blur map indicating the relative amount of perceived local blurriness. We compare the proposed method with six other state-of-the-art...
The reduction of iron ore fines using fluidized bed has attracted more attentions in recent years since it has more advantages in energy consumption and environment protection over the conventional process. To better understand the reduction behavior of iron ore fines in a circulating fluidized bed (CFB), a mathematical model based on unreacted shrinking-core assumption and Rhodes' hydrodynamic models...
This paper represents a method of Content Based Image Retrieval (CBIR) which uses multi-wavelet transform to improve the shape and texture feature extraction and decrease the operand. The theoretical analysis is represented first and the numerical verification and experimental validation using real CT image is showed behind. Both the theoretical analysis and the numerical and experimental results...
