Two-dimensional heat map representing the parameter distribution of the detection threshold (DETECT_THRESH) and the minimally connected regions (DETECT_MINAREA) for the target-detection task in a specific image, thus providing a visual depiction of the state distribution. The depiction of the designed states and actions is presented in the left panel. The current parameter position is denoted as (i, j), and the four adjacent positions are identified as (i+1, j), (i-1, j), (i, j+0.1), and (i, j-0.1).
