A new kind of windows called double-windows, which was developed by convolving conventional cosine window, was proposed. 提出了一类新窗-组合双窗,其由传统的组合余弦窗通过卷积运算生成。
Convolution surface is actually an isosurface of a scalar field defined by convolving skeleton primitives. 卷积曲面实质上是骨架通过卷积方式所定义生成的标量场的一个等值面。
This function convolving with blurred image in spatial domain can get deblurring image. 此函数与模糊图象在空域中进行卷积运算,能得到消模糊图象。
Especially, we give a closed form solution of convolving a triangle skeleton with kernel of a finite support for the first time. 特别是首次解析表达出具有局部支撑核函数下的三角面片骨架势函数,为采用大量的三角面片作为卷积曲面骨架奠定了基础。
After convolving the image model with the edge detection operators of second derivative model, a plane fitting in the least squares sense is used to detect the zero crossing points as edge points. 使用二阶导数型边缘检测算子对图象模型进行卷积后,用均方误差最小的准则对卷积后的图象进行平面拟合,并求出零交点作为图象的边缘点。
To reduce the accumulating of calculation error during the restoration for multiple blurred images, the point spread functions ( PSFs) of each space-invariant blur in the multiple blurred images are combined by convolving all the linear PSFs together. 对空间不变模糊的点扩散函数进行合并,减少多重模糊恢复过程的计算误差累计,通过一次解卷积运算实现多重空间不变模糊图像的恢复。
