1. 5 1 Automatic depth image creation The automatic depth image creation uses a technique called disparity estimation to calculate the disparity image Therefor an image pair is needed which has to meet certain conditions The used algorithms allow using hand taken image pairs because the algorithms are robust against image displacement and color differences between stereo images 5 1 1 Stereo pair generation The automatic depth image generation starts with the creation of image pairs Therefor add two images of the same object which have been taken from different positions into the Picture Gallery Create a stereo image pair by dragging and dropping these images to the 3D Picture Pair area with your mouse ie 30 Picture App C Users ischileAPiclures StereoPictures apan Japans ual lie tec etree IED eu cent lee oan File Tools Windows gt gt e 7 1 Bees oo ee ee a aS gt Al A FIGURE 6 CREATING 3D STEREO IMAGE PAIRS DeCS Media GmbH OCU 3D Picture Introduction to lenticular printing software 10 Note The two frames of a stereo pair should have the same pixel resolution and the same color mode 5 1 2 Depth image calculation First choose the picture pair to estimate depth for by clicking on the pair in the 3D Picture Pairs area Start the depth image calculation by selecting Menu bar gt Tools gt Calculate Depth Map with your mouse A pop up will appear and2. added to the project The following image file formats are supported among others Format compression A compressed file format for bitmap images A file format for graphic images with indexed color palette some compression tiff A lossless file format for bitmap images with some compression Tiff file is in average two times smaller than bmp file mpo A file format for bitmap images used in Fuji FinePix REAL 3D W1 3D camera It contains 2 images in jpg format with special technical information DeCS Media GmbH OCU 3D Picture Introduction to lenticular printing software After you click Open the images files are imported and shown as small preview images in the Picture Gallery 4 THE USER INTERFACI The user interface is split in nine panels or areas 1 Menubar 2 Toolbar 3 3D Picture Pairs 4 Depth View Control 5 Render Settings 6 Image Area 7 Image Toolbar 8 Picture Gallery and 9 Tool Information There are five modes in which the application can be set 1 Gallery mode 2 Input mode 3 Depth mode 4 Rendered mode and 5 3D mode wa 3D Picture App C Users ischiller Pictures StereoPictures Japan Japan f 3 Image Area FIGURE 5 THE USER INTERFACE The main working area is the Image Area Here you can view images and modify the depth map using the tools The Menubar The Menubar holds drop down menus for file operations Tools and to show or hide

7. three viewing modes which assist you in the depth image creation and editing process They can be activated in the Depth view Control The first is the View Interval The main purpose of this mode is to emphasize the contrast of the depth values in the chosen interval Choose the values to your taste to focus on the depth values you are editing The second is the Blend Mode which blends depth and color image It creates a transparent overlay of the depth map over the color image which is especially useful for object border editing The alpha value sets the blending factor The third mode is the so called Replace Mode in which all values not within the interval between Min and Max are replaced by the color image values Note that these three modes are only for viewing and do not affect or modify your actual depth image 6 3 Depth Editing Tools Editing the depth map is done using the tools in the Image Toolbar Tools are displayed when they are available Depth editing tools are displayed in the Depth Mode and for example the Frame Tool is displayed in the rendered view mode to allow selection of image regions for export Tools are selected in the Image Toolbar below the image by clicking on the Tools button Redo buttons Importing and exporting depth images is done using the Import and Export buttons which allows editing the depth image using external tools
