Detecting digital objects and generating object masks on device

A non-transitory computer-readable medium storing executable instructions thereon which, when executed by a processing device, cause the processing device to perform operations comprising:

• receiving a digital image at a computing device;
• generating, utilizing an encoder of a detection-masking neural network, a plurality of feature maps at different resolutions from the digital image;
• detecting, at the computing device utilizing a detection head of the detection-masking neural network and from a first feature map of the plurality of feature maps, a first object of a first size in the digital image;
• detecting, at the computing device utilizing the detection head of the detection-masking neural network and from a second feature map of the plurality of feature maps, a second object of a second size in the digital image, wherein:
• the first object is larger than the second object;
• and
• the first feature map has a lower resolution than a resolution of the second feature map;
• generating, at the computing device utilizing a masking head of the detection-masking neural network, a first object mask for the first object;
• and
• generating, at the computing device utilizing the masking head of the detection-masking neural network, a second object mask for the second object.

A system comprising:

• a memory component:
• one or more processing devices coupled to the memory component, the one or more processing devices to perform operations comprising:
• detecting, utilizing a detection head of a detection-masking neural network, a plurality of potential objects in a digital image;
• determining for each of the potential objects, a class-agnostic objectness score that indicates a confidence that a potential object comprises a general object rather than a background of the digital image;
• identifying one or more objects in the digital image from the plurality of potential objects based on the class-agnostic objectness scores;
• and
• generating, utilizing a masking head of the detection-masking neural network, an object mask for the one or more objects in the digital image.
