Hello experts,
as a beginner in Matlab, i have some problems with the rotation of image from the center point.
Problem defination:
I took the image at 30° from the left side of the picture. Now i want to rotate the image from the center point for -30° in the right direction to achive the proper (flat) image for the analysis.
How can i solve this problem?
Is there any tutorial or scripts or manual for these types of problems?
Thank you in advance.
Best regards

Hi Vivek,
If I have understood correctely and you want to rotate 30 degress counterclockwise you can use the imrotate function e.g newimage = imrotate(oldimage, 30)

Hi John,
thank you for your quick answer.
Actually, i want to tilt my image 30° up from left side, that means vertical rotation. Since my image is 2D, and i want to rotate it in a 3D space, i think my transformation is not a rotation but it should be projection.

You can apply your own custom rotation matrix by using
Or call imtranslate() to shift the rotation point to the center of the image, then call imrotate(), then imtranslate() again to shift it back to where it was.
