This section is much more an evidence when using directly the software than reading explanations. I invite you to read it after trying the software, just to be sure of what occurs.

Choose an image (for example the "DVD.jpg" image that is in the "Demo" sub-directory). Many formats are possible : JPG, PNG, BMP, GIF, etc.. After a short calculation, you should get this (yellow labels were added for this documentation) :

P1 : main panel, display the loaded image in verious state, depending on the current action. At starting, the original image is displayed.
P1b : preview part, display the working selection in various state, depending on the current action. At starting, the final filtered preview part is displayed.

V1 : original preview panel, always display the working selection in its original state.
V2 : edges detection preview panel, always display the image that represent the edges/surface separation on the working selection.
V3 : surfacing preview panel, always display the image that represent what was removed to the original working selection after the surfacing process.
V4 : texturing preview panel, always display the image that represent what was re-added to the surfaced selection after the texturing process.

S1 : edges detection slider, control the edges detection step. When it is moved the edges detection image is displayed in P1 and V2 at the same time.
S2 & S2b : surfacing sliders, control the surfacing step. When it is moved the surfaced working selection image is displayed in P1, while the image that represent what was removed to the original working selection is displayed in V3.
S3 & S3b : texturing sliders, control the texturing step. When it is moved the textured working selection image is displayed in P1, while the image that represent what wasre-added to the surfaced selection is displayed in V4.

B1 : process whole image button, launch the 3 step calculation on the whole image.
B2 : save image button, open a dialog box the save the final denoised image.
B3 : quit button, close the software.
B4 to B9 : zoom button, control de size of the image that is displayed in P1.
B10 : memory safe button, discard few intermediate calculated images (edges detection and surfacing) to save memory on big images. With this option on, intermediate these images can't be displayed any more in the software.
B11 : check for update, search if a new version of the software is available (you should be connected to the web), and if yes, offer you the possibility to automatically download and install.

Mouse control over panels

This section is much more an evidence when using directly the software than reading explanations. I invite you to read it after trying the software, just to be sure of what occurs.

When the mouse is over P1b, only the whole image is displayed, and when the mouse is over P1 but not over P1b, both the whole image and the working selection are displayed. It is then possible to display alternatively the result of the filtering on the working selection by moving the mouse over/out of P1b.

Before a calculation on the whole denoised image :

	Mouse over the Panel V1, V2, V3 and V4	Mouse back to the panel P1
V1	The original version of the working selection is displayed in P1 and in V1 at the same time.	The original version of the whole image is displayed in P1, while the final denoised version of the working selection is displayed in P1b.
V2	The edges detection version of the working selection is displayed in P1 and in V2 at the same time.	The original version of the whole image is displayed in P1, while the edges detection version of the working selection is displayed in P1b.
V3	The surfacing version of the working selection is displayed in P1, while the image that represent what was removed to the original image is displayed in V3.	The original version of the whole image is displayed in P1, while the surfacing version of the working selection is displayed in P1b.
V4	The final denoised version of the working selection is displayed in P1, while the image that represent what was re-added to the surfaced version of the working selection by the texturing step is displayed in V4.	The original version of the whole image is displayed in P1, while the final denoised version of the working selection is displayed in P1b.

After a calculation on the whole denoised image :

	Mouse over the Panel V1, V2, V3 and V4	Mouse back to the panel P1

V3	The surfacing version of the working selection is displayed in P1, while the image that represent what was removed to the original image is displayed in V3.	The previous surfacing version of the whole image is displayed in P1, while the new surfacing version of the working selection is displayed in P1b.
