Abstract:

Aiming at the modeling in digitalized innovation of blue calico patterns, a model for structuring blue calico elements was proposed based on cardinal splines, in which the rigidity of shape was expressed by the tension coefficient, and the concavity and variety were realized by configuration of the knots. Also the expressing of more complex elements by generalization of the model was discussed. The contour tracing technique was employed to extract pattern elements from the images, and the closest model instance was found out based on invariance of the Hu moments, then the model instances were transformed respecting to gravity, acreage and coincidence to meet the pattern elements so as to achieve digitalization of the whole pattern. The mapping function was introduced to create new patterns by filtering the model parameters, and the element model was applied to the pattern skeleton to modify it and bring about more outstanding innovations. The results show that the proposed methods have fine accuracy and efficiency in modeling and reconstruction as well as rich creativity in blue calico pattern innovation.
