We can rotate an image at any angle in counterclockwise direction.axis of the ellipse fitted to the larva outline. This rotation is done using the imrotate.m function in MATLAB. By default, imrotate uses nearest-neighbor interpolation, setting the values of pixels in the final image that are outside the rotated image to 0. Alignment with the horizontal (X) axis allows the use of a polynomial regression for This leads users of imrotate to the wrong conclusion, that "spline" is a valid option for the method parameter of imrotate. But imrotate then only throws an (interp2) error, since a rotated pixel grid is nearly never evenly spaced, as currently needed by interp2 (more precise: needed by _splinen_.m).B = imrotate(A,angle) rotates image A by angle degrees in a counterclockwise direction around its center point.

Sign in to answer this question.Although I only skimmed through your article, I'm pretty sure I used more-or-less the same technique to implement image rotation in MATLAB, for a Masters project I did on medical image registration a few years ago (don't remember why I didn't use the imrotate function… probably because I wanted to implement everything "from scratch").In MATLAB this is easily accomplished with the 'imrotate' and 'sum' commands. First, we zero pad the image so we don't lose anything when we rotate (the images are rectangular so the distance across the diagonal is longer than the distance on a side).Check the Tire Rotation. Here's the rotated tire. Now you know what kind of car I drove across the country some years ago. Ir = imrotate(I,135); imshow(Ir) Quick Ideas?

Rotate image. Syntax. B = imrotate(A,angle) B = imrotate(A,angle,method) B = imrotate(A,angle,method,bbox) Description. B = imrotate(A,angle) rotates image A by angle degrees in a counterclockwise direction around its center point. To rotate the image clockwise, specify a negative value for angle.imrotate makes the output image B large enough to contain the entire rotated image.MATLAB Graphics uses this default coordinate axis. ROTATE(,ORIGIN) uses the point ORIGIN = [x0,y0,y0] as the center of rotation instead of the center of the plot box. Rotate the axis about the Y axis by β followed by a rotation of Y about the Z axis; tan β = n/l and sin β = m, where l, m and n are the components of the unit vector n.Rotation matrix. Again, when we are rotating an object w.r.t its center, we must first bring its center to the origin via translation. Using this method of rotation suffers from the Gimbal lock; hence, a more advanced method called "quaternion rotation" is employed in real-world implementation.Commented: KSSV on 9 May 2017.

Now I want to apply this R and T in I1 to get the ...I have got the coordinates of a point (P) in my main image (2D). The main image (im) is now rotated using imrotate and the angle alpha. Now, I want to know what the coordinates of P are in the rotated image.image with the image processing toolbox function \imrotate" which rotates an image in the counter-clockwise direction >> im rot = imrotate(im,ang); where \ang" is speci ed in degrees. Once you have the image displayed, you can save it in eps format with >> print -deps your filename.eps This produces an eps le in the current directory.
