Embodiment Construction
[0040] The present invention will be described in further detail below in conjunction with accompanying drawing and embodiment, the infrared image source of the embodiment of the present invention comes from IRAY 384*288 infrared focal plane detector, and this detector outputs the infrared image of 384*288 resolution, and this image has There is a characteristic of vertical stripe noise, so in this embodiment, only vertical stripe noise filtering is performed on the image.
[0041] refer to figure 1 As shown, the invention discloses a method for filtering infrared image streak noise, comprising the following steps:
[0042] 1) Receive image data
[0043] The unpreprocessed infrared image output by the infrared focal plane detector is called the original image, and the input image received by this method is the preprocessed image data of the original image.
[0044] The preprocessing of the original image in the example of the present invention includes two-point non-uniformi...
