3d image processing using matlab

Recently, when processing CT images, CT images scan the human body layer by layer, and there are many unnecessary parts in the image, such as the ribs, as a result, there are many unnecessary parts of the 3D reconstruction image. Very difficult to handle. As a result, I thought of a simple method to set unnecessary pi

, including real real and imag imaginary parts, and ABS is the complex of the mold, after this step, the type of f from the plural double into a double, if not this step, MATLAB will give hints, Warning:displaying real part of complex input. The result of the final output is as follows.(5)7. T=log (f+1);After the first few steps, we get the amplitude of the Fourier transform, but the Fourier transform has a very large range of values, MAXF = 2.04e+05,

3D image transition effects implemented using CSS3 animation, css33d This is based onCSS3Animation-based image Transition effects include Flip, Rotation, Multi-flip, Cube, and Unfold. They prove the powerful functions of CSS3 Transform and Transition attributes. As more and more browsersCSS3With continuous improvement

Using Dephi for image processing can be a variety of methods, the most commonly used should be tbitmap, it provides easy access to the image, combined with canvas can be drawn line, draw a circle, image copy and other operations. However, in order to obtain a higher speed, w
