Tutorial
System Requirements
User Interface
First of all download SmartDeblur installer and install it (you need to have admin
rights).
When the installation is complete go to the Start menu and run SmartDeblur - the main window will appear:
The User Interface consists of two main areas - image viewer (in the center) and control panels (on the left side). You can do the following operations with the areas:

- File (left-bottom) - open/save images, see help
- Zoom (status bar) - manage image scale/zoom
- Blur Parameters - allows selecting a blur type and performing the basic image deblurring operations
- Blur Model - contains blur path preview and controls for changing the blur parameters
How to deblur an image
1. Click on the "Open" button to select your image (or use drag & drop).
The currently supported formats are JPEG, PNG, TIFF and BMP
The image will be loaded and shown in the main center area.
Then go to the "Blur Parameters" panel:
2. Choose defect type. There are three cases:

Then go to the "Blur Parameters" panel:
2. Choose defect type. There are three cases:
- Auto-detect Blur - automatically determine camera shake blur
- Out-of-Focus blur - blur due to incorrect focus
- Gaussian Blur - typically it's a blur made by photo editors like Photoshop, Gimp, etc
Auto-detect Blur
In this mode, SmartDeblur will automatically analyze the image and determine the blur
path.
It is suitable for the common motion blur defects (like camera shake) and for
small/medium defocus.
If you need to restore images with large defocus - use "Out-of-Focus" or "Gaussian Blur"
modes.
Then for a quick start you can just click on the "Analyze Blur" button and wait for a while (about 1-2 minutes). When the process is completed, the restored image will be shown in the main area. If the results looks good you just need to choose desired smooth level by moving the slider and clicking the "Apply Smooth" button.
In case of bad results you can increase/decrease the "Blur Size" using the slider and manually select a region for blur estimation by clicking and dragging on the image. Region shall not be too small and shall contain salient structures. See example:
Another option is to use the "Aggressive Detection" checkbox. In this mode SmartDeblur will use some more aggressive strategies to find significant structures on the blurred image. Use this if the image contains clearly visible blur paths (from glares or another point light sources). In this case you need to select a small region containing that light sources:
And the last option to tune the blur analysis results is the "Kernel Editor". Click on this button to open the editor panel (will be shown on the left side).
Use left mouse button to fill in any discontinuous parts of a path, and right mouse button to remove unnecessary parts (like noise, wrongly detected curves, etc).
You can modify the painting pen parameters via the "Line Density" and "Line Width" sliders:

Out-of-Focus and Gaussian Blur
Use these modes to remove a blur caused by mis-focus or Gaussian/defocus blur created by
image processing software. They work in manual mode, so you need to select the right
blur radius.
To start deblurring just load an image and select the appropriate defect type.
Then move the "Radius" slider carefully, a preview result will be displayed (in grayscale to reach high speed). After you tune to the right radius value, release the slider and wait for the full processing (about 5-10 seconds). Finally choose Smooth level with the corresponding slider and release it button.
