Abstract
A method of recognizing an object in an image is provided, the method comprises the following steps. The image having the object is provided, and principal traits of the object are encoded in order to generate a first trait code. The first trait code is compared with data stored in a database so as to obtain a plurality of differences. A minimum of the plurality of differences is found. This method can be applied to synthesize human faces.
Claims24
A method of recognizing an object in an image, comprising steps of:
- providing the image having the object, and encoding principal traits of the object in order to generate a first trait code;
- comparing the first trait code with data stored in a database so as to obtain a plurality of differences;
- and
- finding a minimum of the plurality of differences.
A method for synthesizing an object in an image, comprising steps of:
- providing a plurality of patches;
- providing a trait code being a serial code having at least a value;
- finding the patch corresponding to each of the values in the serial code;
- and
- combining the corresponding patches.
A method of training a trait code, comprising steps of:
- collecting K images having an object respectively, each object has M traits;
- classifying each of the M traits so that the each trait of the K objects is classified into ki trait bases, wherein i=1, 2, . . . , M, and ki≦K and
- extracting N principal traits from the M traits, wherein each of the principal traits includes classified k3 traits bases, and wherein j=1, 2, . . . , N, and kj≦K.
A recognizing and synthesizing system of an object in an image, comprising:
- a database having a datum;
- a sensor receiving a first image;
- a classifier classifying and encoding a first object in the first image;
- and
- a processor comparing the result of encoding with the datum of the database.
