Determine colour ranges
All single frames of the film sequence are analyzed as regards their colours. Each pixel of a single frame has a certain rgb colour value, which is determined and can be changed.
Colour ranges: highlights, midtones, shadows
colour ranges of a frame in comparison to the original
The colour values that have been determined for each frame are divided into three colour ranges (highlights, midtones, shadows). Then each colour range of the frame is being copied, displaying only the pixels of the respective range. All colour values outside the range are transparent. In this way, the former rectangular set of frames turns into a sculpture-like figure, so that shapes and compressions emerge and details of the film’s content are displayed roughly.
example: colour range: shadows of a film sequence
){kind=small}
){kind=small}
){kind=small}
Delete colours
white resp. black colours of a film sequence are deleted
The white or black colour components of the frame are deleted, while all other ranges remain in their original colour, i. e. they are extracted. Changes in these extracted elements, such as tracking shots or movements, become comparable in this mode by choosing a suitable background.
example: white colours of a film sequence are deleted
){kind=small}
){kind=small}
){kind=small}
){kind=small}
){kind=small}
