Inspecting an image
Start LEOWorks 3.0
Open the file LS7_190_31_09062001_B01.tif
To inspect the distribution of the pixel values in the image choose Histogram.
It is seen that the pixels have values in the range of 62 to 137. The pixel values are visualised in the gray scale image where pixel value 0 is shown as black and pixel value of 255 is shown as white. Therefore the image is gray with little contrast.
Choose View/Image Values to open a window with the matrix of the pixel values.
