Depth estimation is the task of predicting depth of the objects present in an image.

About Depth Estimation
Use Cases
Depth estimation models can be used to estimate the depth of different objects present in an image.

Estimation of Volumetric Information
Depth estimation models are widely used to study volumetric formation of objects present inside an image. This is an important use case in the domain of computer graphics.

3D Representation
Depth estimation models can also be used to develop a 3D representation from a 2D image.
