31 May 2009	freehanddraw Draw smooth lines freehand on images or plots; return the handle and xy data of the line object. Author: Brett Shoelson	Very good work works very nicely !!! Has anyone managed to merge the line object to the actual image one is drawing upon.... i.e change the value of the actual image pixels .. Thanks

03 May 2011	High accuracy optical flow High accuracy optical flow using a theory for warping	shreyas	Hey, Its a really nice piece of work, I am getting stuck at one part because, I want to reduce the number of points/resolution for which optical flow is computed,I believe that this will make the code faster. Would be grateful,if anyone who has done this provides me with some help.	Comment only
08 Apr 2011	freehanddraw Draw smooth lines freehand on images or plots; return the handle and xy data of the line object.	Brett Shoelson	AA, IMFREEHAND didn't exist when I wrote FREEHANDDRAW. I'm happy to see that you're using the new Toolbox functionality!	Comment only
06 Apr 2011	freehanddraw Draw smooth lines freehand on images or plots; return the handle and xy data of the line object.	AA	how is the following different from what the file outputs? figure; imshow('pout.tif'); h = imfreehand;data=get(h); xydata=get(data.Children(4)); x=xydata.XData; y=xydata.YData; figure; plot(x,y,'-.') These statements give the x, y data of an arbitrary freehand drawing on a figure.	Comment only
14 Mar 2011	High accuracy optical flow High accuracy optical flow using a theory for warping	rh_sh	Hi all,I have a question.I compute the optical flow(u ,v) using LK and HS method. Now I want to compute the average angular error(AAE).But I don't know how.Do I need the ground truth optical flow (in .pcm file format)for compare the flow ? Or any other way to compute the angular error? thank u all.	Comment only
30 Mar 2010	High accuracy optical flow High accuracy optical flow using a theory for warping	Omid Aghazadeh	I have made some minor modifications to your implementation of Brox's algorithm: - Reflecting boundary conditions corresponds to mirror-extending the images. This can remove some of "unwanted" spurious flows at image boundaries. - Added color channels (and different color spaces) - 500 SOR Iterations is too much! If I remember correctly, Brox mentions much less SOR iterations. You can safely decrease it to around 50(or even less). Let me know if you want me to send the modified code to you(Visesh). Regarding the higher errors on the results: - If I'm not mistaken, this implementation does not assume spatio-temporal smoothness(it's not 3D) and does not work on more than 2 images . In order to get nicer results you have to extend it to the 3D case. I recently realized that Brox has already put his binaries(both for the ECCV04 and CVPR09 papers) online!	Comment only
