Processing circuitry (e.g., GPU) obtains a first MSAA intermediate buffer from a rendering of a first image, the first MSAA intermediate buffer includes a plurality of subsamples for each pixel of the first image. The processing circuitry determines, for a first pixel of the first image, a first surrounding subsample pattern based on first subsamples in a surrounding region of the first pixel. Further, the processing circuitry obtains, based on the first surrounding subsample pattern, a first blending weight vector for a first location among a plurality of locations that define output pixel locations within the first pixel for upscaling the first pixel to a plurality of output pixels in an upscaled image of higher resolution than the first image. The first blending weight vector includes first blending weights respectively for first candidate subsamples associated with the first pixel. The processing circuitry generates the upscaled image accordingly.

A medical tube-tracing method is described herein, where a curve is fitted to pixels of a binary segmentation mask representing a medical tube in an X-ray image. The curve may then be used to generate a more precise and realistic representation of the medical tube in the X-ray image. A location of the tube may be saved as a set of coordinates, which may reduce an amount of processing and computation performed by software applications to display the medical tube in the x-ray image, and provide the software applications more freedom and flexibility in displaying the medical tube.

Implementations set forth herein relate to modifying a generative output of an application according to an input gesture that is performed without necessarily interacting with a GUI element that is rendered separate from a generative output (e.g., a GUI element separate from a natural language output generated using an LLM or an image generated using an image diffusion model). Various different input gestures can be performed by a user to refine a generative output to be simpler, more complex, to include an image, to modify a generated image, and/or otherwise modify the generative output. In some implementations, an input gesture can be processed as one or more predetermined gestures, and/or an input gesture can be interpreted per case using an available model for interpreting such gestures. In this way, models for interpreting gestures and/or refining generative output can be enhanced through further training of such models.

The present disclosure relates to systems, non-transitory computer-readable media, and methods for aligning curves to precise geometric shapes using a geometry matching algorithm. For example, the disclosed systems generate a set of discrete points along a curve depicted in a digital image by sampling the curve spanning between a first corner and a second corner depicted in the digital image. The disclosed systems determine an order for comparing the set of discrete points with a first geometry and a second geometry by comparing a centroid of the curve with a centroid of the first geometry and a centroid of the second geometry. The disclosed systems also determine, according to the order, a first similarity of the curve to the first geometry and a second similarity of the curve to the second geometry. The disclosed systems generate curve segments that align with one of the first geometry or the second geometry.
