Systems and methods for instance segmentation
The invention provides the techniques and systems that allow for the identification and classification of objects (i.e., humans) in images using a predictive segmentation model. More specifically, human forms are identified within an image by generating pixel-level bounding boxes for each possible object and using offsets and segmentation masking. In some instances, embodiments of the invention use an identified floor plane that intersects with a bounding box to identify a three-dimensional position for the intersection point, which can then be assigned to the human form and represent its depth within the image.

Automatically setting zoom level for image capture
A system obtains an image from a digital image stream captured by an imaging component. Both a foreground region of interest and a background region of interest present in the obtained image are identified, and the imaging component is zoomed out as appropriate to maintain a margin (a number of pixels) around both the foreground region of interest and the background region of interest. Additionally, a position of regions of interest (e.g., the background region of interest and the foreground region of interest) to improve the composition or aesthetics of the image is determined, and a composition score of the image indicating how good the determined position is from an aesthetics point of view is determined. A zoom adjustment value is determined based on the position of the regions of interest, and the imaging component is caused to zoom in or out in accordance with the zoom adjustment value.
GENERATING AN IMAGE MASK USING MACHINE LEARNING
A machine learning system can generate an image mask (e.g., a pixel mask) comprising pixel assignments for pixels. The pixels can he assigned to classes, including, for example, face, clothes, body skin, or hair. The machine learning system can be implemented. using a convolutional neural network that is configured to execute efficiently on computing devices having limited resources, such as mobile phones. The pixel mask can be used to more accurately display video effects interacting with a user or subject depicted in the image.
