Title: TWO-DIMENSIONAL IMAGE DEPTH-OF-FIELD GENERATING METHOD AND DEVICE
Abstract:
A two-dimensional image depth-of-field generating method and device. The method comprises: obtaining a target image, performing image class classification processing on the target image to obtain a plurality of corresponding image classes, and calculating a corresponding maximum definition value for each image class (S1); separately obtaining objects of each image class, estimating definition values of the objects of each image class, and classifying the objects of each image class according to the maximum definition value thereof (S2); estimating a depth value of the objects of each image class according to the definition values of the classified objects of each image class by means of a depth value estimation algorithm (S3); estimating a depth-of-field value of the objects of each image class according to the depth value of the objects of each image class by means of a depth-of-field value estimation algorithm (S4); and storing the depth-of-field value after correction and forming an image depth-of-field. The present invention resolves the problem in the prior art of image distortion occurring in obtaining a single-viewpoint depth-of-field. A depth-of-field is generated from a two-dimensional image, to reduce image distortion, improve image stability, and satisfy user requirements.
