Description

technical field [0001] The present invention relates to the field of image processing, in particular to a focal plane array processing method, device, storage medium and processor. Background technique [0002] At present, the focal plane array can be a focal plane staring array, and all existing cameras use a focal plane staring array. The focal plane array will be accompanied by aliasing phenomenon in the discrete sampling process. For example, when sampling, the frequency is not high enough. The sampled points not only represent the sample value of the low-frequency signal in the signal, but also represent the sample value of the high-frequency signal. When the signal is reconstructed, the high-frequency signal is replaced by the low-frequency signal. The two waveforms overlap completely, causing severe distortion of the signal. [0003] The existing imaging quality evaluation methods of focal plane arrays are all based on empirical qualitative evaluation, without consi...
