Recently, we have studied bilinear and bicubic algorithms for image scaling during video stream playback. Here is an algorithm that doubles the image in the latest project. For algorithm optimization, you can consider using the
In the process of image geometric transformation, the commonly used interpolation methods are nearest neighbor interpolation (near sampling method), bilinear interpolation and three convolution method. nearest neighbor interpolation:
This is one of
In the field of film and television production, the problem of enlarging low-resolution images to high-resolution images is often involved, and sometimes the issue of adjusting non-square pixels to square pixels is also involved. This chapter

In the previous fsaa introduction, the triangular surface distortion (Aliasing) Question. However, in this article, the main method mentioned is to eliminate the aliasing

Clear;lena=imread (' a1.bmp '); three lines below specify a zoom multiplier of 0.5, that is 0.5 times times the length and width of the original image,% using three interpolation methods, that is, nearest neighbor interpolation (default), bilinear
Photozoom is a smart zoom picture software, many users in the first use of photozoom, found that the image is located above the area has four different ways of preview options. Because many beginners do not understand the role of these four buttons,
The normal plane effect can be achieved by changing the horizontal and vertical coordinates. With the addition of depth, 3D effects can be visually produced. The program simulates such a three-dimensional space, and the images in the space are
The program simulates such a three-dimensional space, and the images in the space are displayed according to the three-dimensional coordinates.
I have seen a 3DRoom effect a long time ago and it is implemented using complex computing.
