Robust image-based three-dimensional sensing techniques

A system comprising:

• a processor;
• and
• a memory storing instructions which, when executed by the processor, cause the processor to perform operations including:
• capturing a plurality of images of an object from a plurality of viewpoints;
• determining, for each respective image of at least a subset of the plurality of images, a respective first region that contains the object;
• determining, for each respective image of the at least a subset of the plurality of images, a plurality of visual features of the object within the respective first region;
• determining, for each respective image of the at least a subset of the plurality of images, a segmentation mask of the object based on the plurality of visual features;
• determining, using a first machine learning model, a first three-dimensional representation of the object based on the plurality of images and the segmentation masks;
• and
• determining a second three-dimensional representation of the object based on the first three-dimensional representation.
