A de-noising method based on L0 gradient minimization and guided filter for ancient Chinese calligraphy works on steles

Background: A multi-scale multidirectional image fusion method is proposed, which introduces the Nonsubsampled Directional Filter Bank (NSDFB) into the multi-scale edge-preserving decomposition based on the fast guided filter. Methods: The proposed method has the advantages of preserving edges and extracting directional information simultaneously. In order to get better-fused sub-bands coefficients, a Convolutional Sparse Representation (CSR) based approximation sub-bands fusion rule is introduced and a Pulse Coupled Neural Network (PCNN) based detail sub-bands fusion strategy with New Sum of Modified Laplacian (NSML) to be the external input is also presented simultaneously. Results: Experimental results have demonstrated the superiority of the proposed method over conventional methods in terms of visual effects and objective evaluations. Conclusion: In this paper, combining fast guided filter and nonsubsampled directional filter bank, a multi-scale directional edge-preserving filter image fusion method is proposed. The proposed method has the features of edge-preserving and extracting directional information.

The Past

Our research in the past 40 years has identified beneficial effects of Chinese calligraphy handwriting (CCH) practice on visual attention, cognitive activation, physiological slowdown, emotional relaxation and behavioural change. We hypothesised that these outcomes may constitute a compressive set of foundations which could impact several traits of Chinese personality within the context of Confucian culture and values. Here, we give a brief overview of the background of CCH and its effect in the cognitive, physiological and bio-emotional domains. We then provide empirical evidence showing strong association of CCH and personality traits and discuss the results in the contexts of calligraphy practice and Confucian literati personality, Confucianism and Chinese personalities as well as calligraphy writing and tool-using psychological theory.
