Imwarp和imtransform
WebB = imtransform(A,tform) transforms image A according to the 2-D spatial transformation defined by tform, and returns the transformed image, B.. If A is a color image, then imtransform applies the same 2-D transformation to each color channel. Likewise, if A is a volume or image sequence with three or more dimensions, then imtransform applies the … Webimtransform 函数会自动平移输出图像的原点，以尽可能多地显示变换后的图像。如果您使用 imtransform 进行图像配准，语法 B = imtransform(A,tform) 可能会产生意外的结果。 …

WebYou can use this object as input to imwarp to control the output limits and grid spacing of a warped image. example. Rout = affineOutputView (sizeA,tform,"BoundsStyle",style) also specifies constraints on the spatial limits of the output view, such as whether the output view should completely contain the output image or whether the output view ... WebMar 4, 2024 · 1. I am using imtransform to distort images with conformal maps as proposed in exploring a conformal mapping. It works fine but Matlab shows a warning that imtransform is not recommended and imwarp should be used instead but the transfer from imtransform to imwarp is difficult. Could someone transfer the distortion process with …
WebR2024b: Not recommended. Discouraged Usage. Recommended Replacement. This example creates an affine2d object from transformation matrix T in the postmultiply convention. T = [2 0.33 0; 0 1 0; 0 0 1]; tformPost = affine2d (T); This example creates an affinetform2d object from the transpose of the transformation matrix T. WebJan 8, 2013 · OpenCV comes with a function cv.resize () for this purpose. The size of the image can be specified manually, or you can specify the scaling factor. Different interpolation methods are used. Preferable interpolation methods are cv.INTER_AREA for shrinking and cv.INTER_CUBIC (slow) & cv.INTER_LINEAR for zooming.

Again, this is shown in the examples for imregtform.
WebB = imwarp (A,tform) transforms the numeric, logical, or categorical image A according to the geometric transformation tform. The function returns the transformed image in B. B = imwarp (A,D) transforms image A according to the displacement field D. [B,RB] = imwarp (A,RA,tform) transforms a spatially referenced image specified by the image data ...
