GRSL - 2013 - A Robust Directional Saliency-Based Method for Infrared Small-Target Detection Under Various Complex Backgrounds

对问题的假设

• 把问题刻画成 显著性检测，假设 目标是 isotropic Gaussian-like shape，而 background clutters are generally local orientational
  • formulate this problem as salient region detection, which is inspired by the fact that a small target can often attract attention of human eyes in infrared images.
  • This visual effect arises from the discrepancy that a small target resembles isotropic Gaussian-like shape due to the optics point spread function of the thermal imaging system at a long distance, whereas background clutters are generally local orientational.

进一步假设：

It is legible that Gaussian spots are highlighted as salient regions while strips are inhibited, which accords with our visual effects.

先做 SODD，然后在 SODD 的基础上做 PFT
