Ghosal-type hematodiaphyseal dysplasia has been first described in 1986, as a steroid-dependant anemia with endosteal broadening of the long bone’s diaphyses and metaphaphyses, which makes a distinction with the periosteal reaction in Camuratti- Engelmann’s disease and with Caffey’s disease. Extreme pallor is first noticed and leads to search for palpable thick long bones that are not always clinically obvious. The transmission of this rare entity seems to be autosomal recessive, with a common racial background from the Middle East and the Indian subcontinent. Anemia is considerably improved by steroids, which allow to avoid blood cells transfusions, but a minimum maintenance dose is necessary to keep the hemoglobin at a normal level probably during the whole life, involving iatrogen complications. The mechanism of anemia and the genetic cause of the disease are yet unknown. 展开更多

本文在Zernike矩的亚像素边缘检测算法的基础上,通过修改Prata算子和提出了一种比q-recursive更快的递归关系,提出来一种改进的算法。新算法克服了Ghosal在亚像素边缘检测时存在高阶矩时较高的计算成本和数值不稳定性的不足。实验结果表... 本文在Zernike矩的亚像素边缘检测算法的基础上,通过修改Prata算子和提出了一种比q-recursive更快的递归关系,提出来一种改进的算法。新算法克服了Ghosal在亚像素边缘检测时存在高阶矩时较高的计算成本和数值不稳定性的不足。实验结果表明,该算法的运算速度与精度比Ghosal算子和Prata算子有较大的提高。 展开更多
