Image display method, electronic device, and non-transitory computer readable recording medium for quickly providing simulated two-dimensional head portrait as reference after plastic operation

Abstract

An image display method executes on an electronic device. The image display method establishes an original three-dimensional head portrait model with a plurality of first feature points according to frontal face information of a face, wherein the first feature points form a plurality of first grids on the original three-dimensional head portrait model, and the first feature points define a plurality of feature models on the original three-dimensional head portrait model; establishes a texture mapping figure according to a left face image, a right face image, and the first grids; obtains a replacement model according to a feature replacement instruction; replaces a selected feature model of the feature models with the replacement model to generate a simulated three-dimensional head portrait model; generates a simulated two-dimensional head portrait image according to the simulated three-dimensional head portrait model and the texture mapping figure; and displays the simulated two-dimensional head portrait image.
