Auto-image alignment system and method based on identified anomalies

The present invention provides a novel technique and is particularly useful in medical imaging, although a number of fields may benefit from its application. In one aspect of the technique, a user identifies anomalies or, more generally, features in at least two different comparable images either by computer aided techniques or by manual identification. Once the features are identified they are numbered, sized, and a key location for the feature, such as the middle of an anomaly, may be estimated. Once this location is determined, a location marker is used to perform registration of the images. When comparisons are to be conducted, then, the registration is used to effectively anchor the images with respect to one another to facilitate paging between the images and reduction of eye movement.

Computer-aided techniques for iteratively generating designs

In various embodiments, a generative design application iteratively generates designs via a generative design process. In operation, the generative design application performs one or more layout operations on virtual objects based on a first set of design constraints to generate a first design. The generative design application then modifies the first set of design constraints based on feedback associated with a mid-air representation of the first design displayed in a virtual reality environment to generate a second set of design constraints. Subsequently, the generative design application performs one or more layout operations on the virtual objects based on the second set of design constraints to generate a second design that achieves design goal(s). Advantageously, enabling a designer to incrementally indicate design goal(s) as constraints via a virtual reality environment instead of as a predetermined objective function reduces both the time and effort required to generate designs.
