You can also view the report online: <a href="https://wiki.blender.org/index.php?title=User:Tianwei37/Report_&_Blog/Week_8&action=edit&redlink=1" class="">https://wiki.blender.org/index.php?title=User:Tianwei37/Report_%26_Blog/Week_8&action=edit&redlink=1</a>.</div><div class=""><br class=""></div><div class="">== What I did this week: ==</div><div class="">* A<span style="font-family: HelveticaNeue;" class="">dd keyframe selection in multi-view mode. With keyframe selection and witness camera support, the re-projection error can be as low as 0.3 pixels for the tested video clips. Although re-projection error is not a authentic metric for reconstruction accuracy, it sort of shows the performance of the solver. </span></div><div class=""><span style="font-family: HelveticaNeue;" class=""><br class=""></span></div><div class=""><span style="font-family: HelveticaNeue;" class="">* A</span><font face="HelveticaNeue" class="">dd new color theme for linked tracks and selected linked tracks. If tracks across clips get linked, they are shown in a different color from normal tracks.</font></div><div class=""><font face="HelveticaNeue" class=""><br class=""></font></div><div class=""><font face="HelveticaNeue" class="">* Discuss the correspondence UI issue with my mentor. We are agreed on making a separate mode for specifying correspondences across clips. Potential benefits of this independent mode in space clip includes: (quoted from Sergey)</font></div><div class=""><div class=""><div class="">1. remove hacks of searching for another clip across the whole window </div><div class=""><div class=""></div><div class="">2. you can show only options and buttons which are relevant to correspondence mode (link/unlink tracks) </div></div><div class=""><div class=""></div><div class="">3. you can visualize with a parenting line what track corresponds to what</div></div></div><div class=""><div style="font-family: HelveticaNeue;" class="">4. for both clips you'll know where to get list correspondences from</div></div></div><div class=""><br class=""></div><div class="">* Work on the UI icon stuff and reading docs about adding icon. Add a new icon for correspondence mode.</div><div class=""><br class=""></div><div class="">* Start the UI work of multi-view reconstruction. It is focused no the correspondence mode in space clip.</div><div class=""><br class=""></div><div class="">== What I will do next week: ==</div><div class="">* The primary goal for the next few weeks is to make a decent UI for correspondence and multi-view reconstruction. I will start by drawing a double-clip view side by side in movie clip editor. The correspondence mode will be simple and solely focused for specifying correspondences.</div><div class=""><br class=""></div><div class="">* A secondary goal is to gather bug reports and user experience from artists about the multi-view solver. So a series of bug fixes and improvements will be done in parallel.</div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Thanks,</div><div class="">Tianwei</div></body></html>
