Skyceiver Image Enhancement

Three groups of enhancement functions are available within Skyceiver .

The first group is simply applying a “false color” to each gray level of the image. Enhance functions of the first group are B/W linear enhancement, Color enhancement and Bit Slicing. The memory size used for the image is (width * height) plus some bytes for the TIFF header.

The only function of the second group is the “Sea masking (TV)” enhancement. The image in memory is modified by applying the sea/land mask inside the LSB bit of the image and then the “false color” to each gray level is applied. The memory size used for the image is (width * height) plus some bytes for the TIFF header.

The third group contains two enhancement functions: DEM and true color presentation. In these functions, the picture is displayed in “true color” mode, using 24 bits per pixel. The memory size used for the image is therefore (width * height * 3) plus some bytes for the TIFF header.

While in DEM presentation, a special 3D mode can also be activated, to see the pictures 3-dimensionally.

The Enhancements bar is always present at the righthand side of the screen, and specific enhancement sections can be examined by clicking on the drop down arrows with the section headings: grid, ecmwf, mpef, composition, satellite, and background.

Enhancement operations can be on both still images and loops of images.

Once an enhancement is applied it is memorized for that loop sequence up to the next change of this enhancement. This feature allows the enhancing of images in black and white and further color enhancement on the same loop. The gray part of the image remains enhanced.
