An inference model construction method obtains a distribution of control points pertaining to a reference state and a distribution of the control points pertaining to a defined state with respect to a defined representation model. The method extracts a first feature value based on the distribution of the control points pertaining to the reference state. The method machine-learns the distribution of the control points pertaining to the defined state while using, as a label, the first feature value, and constructs an inference model based on a result of the leaning performed with respect to a plurality of the defined representation models.

Certain embodiments involve a graphics manipulation application using brushstroke parameters that include a maximum alpha-deposition parameter and a fractional alpha-deposition parameter. For instance, the graphics manipulation application uses an alpha flow increment computed from the maximum alpha-deposition parameter and the fractional alpha-deposition parameter to compute an output canvas color. In some embodiments, if the current canvas opacity exceeds or equals the maximum alpha-deposition parameter, the current canvas opacity is selected as the output canvas opacity. Otherwise, the graphics manipulation application computes the output canvas opacity by increasing the current canvas opacity based on the alpha flow increment. The graphics manipulation application updates a canvas portion affected by a brushstroke input to include the output canvas opacity and the output canvas color.

Using a computer-implemented intermediary by which contouring performed by two participants, such as two physicians, can be compared. First, contouring performed by each participant can be compared to contouring performed by the intermediary. Then, by way of the common intermediary and a transitive analysis, contouring performed by each participant can be compared.

In implementations of path-constrained drawing with visual properties based on a drawing tool, a digital artwork editing system includes a user interface in which a constraint path can be designated in a digital artwork. A stroke input can be sampled as it is drawn with a drawing tool and for each processing interval of the stroke input, a start point of the stroke input and a tangent line to the constraint path is determined. An end point of the stroke input is projected onto a parallel line that is through the start point and parallel to the tangent line, and a stroke is rendered along this line. Hence, the stroke is rendered based on the stroke input in a piecewise linear fashion, simultaneously constrained by the constraint path and rendered based on how the drawing tool is used.

In some embodiments, a computer-implemented method of presenting an achievable eyebrow is provided. A computing system receives an indication of an eyebrow mimetic for a subject. The computing system positions the eyebrow mimetic on an image of a face of the subject. The computing system determines an achievable eyebrow by determining one or more modifications to a bare eyebrow of the subject within maximum modification parameters to make the bare eyebrow more like the eyebrow mimetic. The computing system generates a presentation of the achievable eyebrow.

A monitor is installed in an eye of a robot, and an eye image is displayed on the monitor. The robot extracts a feature quantity of an eye of a user from a filmed image of the user. The feature quantity of the eye of the user is reflected in the eye image. For example, a feature quantity is a size of a pupillary region and a pupil image, and a form of an eyelid image. Also, a blinking frequency or the like may also be reflected as a feature quantity. Familiarity with respect to each user is set, and which user's feature quantity is to be reflected may be determined in accordance with the familiarity.

A system and method for extending bounds of straightened and enlarged images is described. A user interface of an image editing application exposes an image to a user for editing. The user positions the image in the user interface and the image editing application generates a frame in the user interface to identify boundaries of a final image in the user interface. The image editing application then automatically determines an empty area within the frame, applies a fill operation to the empty area within the frame, and updates the image in the user interface to reflect results of the fill operation.
