Abstract

Systems and methods including one or more processors and one or more non-transitory storage devices storing computing instructions configured to run on the one or more processors and perform: generating a mask of an object using one or more images; generating a 3D model of the object using the mask of the object; simulating an artificial 3D capture environment; generating an artificial surface for the object in the artificial 3D capture environment; transferring the artificial surface for the object to the one or more images; and blending the artificial surface for the object with a real-world surface in the one or more images. Other embodiments are disclosed herein.

training a machine learning algorithm on one or more training images;

identifying, using the machine learning algorithm, as trained, (1) the object in the one or more images and (2) objects other than the object in the one or more images;

removing the objects from the one or more images; and

after removing the objects from the one or more images, generating the mask from only the object in the one or more images.

4. The system of claim 3 ,

wherein the machine learning algorithm, as trained, comprises a neural network configured identify an automobile;

wherein the one or more training images comprise one or more voxel models; and

wherein at least a portion of the one or more training images are labeled with:

a make of the automobile;

a model of the automobile; and

a body type of the automobile.

5. The system of claim 1 ,

wherein the mask comprises at least a portion of the one or more images, and

wherein the one or more images comprise images taken radially around the object; and

the generating the 3D model of the object using the mask of the object comprises performing volume carving using at least the portion of the one or more images to create a voxelized model of the object.

6. The system of claim 1 , wherein the generating the artificial surface for the object in the artificial 3D capture environment comprises:

simulating reflections and shadows for the object in the artificial 3D capture environment by reflecting artificial light for the artificial 3D capture environment off of the 3D model of the object;

rendering the artificial surface for the object using path trace rendering at a lower resolution than a display resolution; and

supersampling the reflections and shadows at the display resolution; and

wherein the artificial light is generated using a 3D image map of a real-world capture environment where the one or more images were taken.

7. The system of claim 1 , further comprising:

facilitating displaying a 3D display of the object using the one or more images, the 3D display comprising the artificial surface for the object and the real-world surface for the object.

8. The system of claim 7 , further comprising:

receiving a zoom selection point selected by a user on the 3D display of the object;

facilitating zooming the 3D display of the object into a zoomed 3D display of the object; and

facilitating rotating the zoomed 3D display of the object around the zoom selection point.

9. The system of claim 1 , wherein the artificial 3D capture environment comprises a 3D rendering of a real-world capture environment where the one or more images were taken.

10. The system of claim 1 , wherein the generating the mask of the object comprises:

receiving an image of the object;

determining a respective pixel intensity for each respective pixel in the image; and

when the respective pixel intensity of a respective pixel of each respective pixel is above a predetermined threshold, labeling the respective pixel as not the object.

11. A method comprising:
