Hi Wu,

detectSURFFeatures is a function in Computer Vision System Toolbox. You need to have that toolbox to run this code.

Thanks,
Bruce

Hi Bruce,

I can't find the function detectSURFFeatures,could email it to me? my email is hawf1988@163.com.

Best wishes

Hi val,

I suggest changing the settings for feature detection to capture more features. That will help increase the likelihood that vision.GeometricTransformEstimator will work properly.

Thanks,
Bruce

Dear Bruce,

In the 1st demo, what shall I do if the distorted image is flipped? It looks that none of the 3 transforms in vision.GeometricTransformEstimator work for me, i.e. I always get one bad match (in addition to 5 good) which throw recovery off.
Thanks

Deepanshu,
The offset in "MarchCard.m" is for creating a visualization. We combine the image of the card and the image of me holding the card. Then we project the feature points found in the card image into the combined image, so that we can draw the lines properly. HTH!

Asking about Match Card.m.What is the use of offset pts in reference image?

01 Apr 2013 Bruce Tannenbaum

Hi Ahmed,
Every deck of cards has a slightly different pattern to the face cards. ReplaceCard only works with the deck of cards from MathWorks, which we give away at events and tradeshows. But you can make it work with your object by replacing the reference image with one of your choice. The reference image is "MWqueen_crop_small.bmp".

Hope this helps!

Hi i tried to use replacecard() but it does not locate the object. Video runs fine but no detection. Bruce Tannenbaum can you help. I want to detect kitchenware object in videos.
