the creativity of a special effect is unpredictable, but the rendering effect and operation time can be polished to the extreme.

Among them, the rendering effect depends on the improvement of CV (computer vision) +CG (computer graphics) algorithms, while the operation time depends on the optimization of models.

For a computer, CV algorithm can make it accurately "understand" the content in a photo. From the fit of special effects and the accuracy of real-time tracking to the resolution improvement and style change of the whole image, they all belong to the category of CV algorithm.
