Embodiments of the present disclosure relate performing registration of a first image to a second image where the first image is undistorted to linear space before applying a geometric transformation matrix to modify the first image to align with the second image. The geometric transformation matrix may be a linear matrix that causes the undistorted version of the first image to make translation movement, rotational movement or both. The undistorted and modified first image is then reverted back to nonlinear distorted space. Then the reverted first image may be warped to better align with the second image for fusing with the second image. In this way, visual distortions in the fused image such as wobbling may be reduced or eliminated.

Linear transform of undistorted image for fusion

Embodiments relate to circuitry for warping image pyramids for image fusion. An image fusion circuit receives captured images, and generates image pyramids corresponding to the received images to be used for image fusion. A warping circuit warps the first image pyramid based upon one or more warping parameters to align the first image pyramid to the second image pyramid. The warping circuit is a multi-scale warping circuit configured to warp each level of the first image pyramid, using a first warping engine that warps a base level of the image pyramid, and at least one addition warping engine that warps a plurality of scaled levels of the image pyramid in parallel with the first warping engine.

Multi-scale warping circuit for image fusion architecture

In a graphics pipeline of a graphics processor, a method for a unified primitive description for rasterization. The method includes receiving a group of primitives from a graphics application, wherein the group includes different types of primitives and the types of primitives include line primitives, point primitives and triangle primitives. For each of the types of primitives, the method includes generating a corresponding parallelogram, wherein the parallelogram has four sides disposed along an x-axis and a y-axis, and computing an inside y-axis mid point and an outside y-axis mid point based on the four sides. The parallelogram is controlled to represent to each of the primitive types respectively by adjusting a location of the inside y-axis mid point or the outside y-axis mid point.

Parallelogram unified primitive description for rasterization

The present invention is a method for operating a data processing system to generate a sequence of test states containing a predetermined set of states and/or transitions for use in testing an integrated circuit or the like. The method minimizes the number of additional states and/or transitions contained in the test sequence while preserving any constraints on the sequence of transitions that may be applied to the circuit to be tested. The present invention operates by defining a graph containing the predetermined set of states and/or transitions. The states are the vertices of the graph and the transitions are edges of the graph. The graph is then augmented if needed with additional states and/or transitions. The additional states and/or transitions assure the existence of an Eulerian Path through the graph. The additional states assure that the graph is connected, and that each vertex in the graph, with the possible exception of two vertices, has the same number of inbound and outgoing transitions. The Eulerian Path is then traced to provide a sequence of states that includes the input list of states and/or transitions.
