Abstract: A first image is projective transformed into a reference image by using a projective transformation matrix on each pixel of the first image. A projective transformation matrix for transforming a tilted image n into a central image G0 is computed based on positions of combinations of twelve corresponding points indicated in a combination of the central image G0 with the tilted image n. The computed projective transformation matrix is then employed to perform a projective transformation of the tilted image n. A projective-transformed tilted image n1 is created thereby.

Abstract: A call method is provided. In the call method, a first account is associated with a number of called party devices. A calling party device may call the number of called party devices by using the first account. When receiving calling, a called party device that is difficult to carry, such as a smart speaker or a smart television, may detect whether a distance to a smartwatch or a mobile phone having a same account is less than a distance threshold. If the distance is less than the distance threshold, the smart speaker or the smart television may output an incoming call prompt. If the distance is not less than the distance threshold, the smart speaker or the smart television ignores the received calling, and makes no response to the calling.
