Description Streak is an image artifact from the failure of other row and line correlated noise clean up algorithms, such as thm.deplaid and destreak, caused by boundries of hot and cold areas in radiance space. It shows up predominantly in decorrelation stretch images as line and row correlated color changes of multiple pixel widths in emissivity images. It generally occurs because the temperature masks used in these algorithms do not function perfectly.
