总之,convolve() 适用于较小的内核,而 convolve_fft() 由于使用了 FFT,对于较大的内核更为高效。 https://docs.astropy.org/en/stable/convolution/

还有一点要提下,就是Winograd这个算法发明出来其实是用来加速Convolution操作的,所以计算变换矩阵也是从Convolution角度去计算,而计算出来的变换矩阵在做一点小变动之后,也可以直接应用在深度学习的...的乘法次数就能达到加速的目的 3.2、Winograd F(2,3)变换矩阵推导现在来看下具体到的变换矩阵是如何得到的。...然后看...

Not because we are doing astronomy (though we are imaging the Earth from space), but because the NaN treatment in astropy.convolution.convolve() is so good. 👍 3 astrofrog mentioned this issue Feb 23, 2017 Convolution consistency astropy/astropy#5782 Merged 4 tasks Member eteq ...
