Abstract: A system and process for determining the similarity in the shape of objects is presented that generates a novel shape representation called a directional histogram model. This shape representative captures the shape variations of an object with viewing direction, using thickness histograms. The resulting directional histogram model is substantially invariant to scaling and translation. A matrix descriptor can also be derived by applying the spherical harmonic transform to the directional histogram model. The resulting matrix descriptor is substantially invariant to not only scaling and translation, but rotation as well. The matrix descriptor is also robust with respect to local modification or noise, and able to readily distinguish objects with different global shapes. The typical applications of the directional histogram model and matrix descriptor include recognizing 3D solid shapes, measuring the similarity between different objects and shape similarity based object retrieval.

First and second discrete curves are received. A rotational shift between the first discrete curve and the second discrete curve is estimated based on the first discrete curve and the second discrete curve. A cumulative rotational shift is updated based on the estimated rotational shift. A rotationally shifted version of the second discrete curve is generated based on the cumulative rotational shift. The estimating, updating, and generating are performed in an iterative manner using the respective rotationally shifted discrete curve for each iteration until a stopping condition occurs, thereby determining a final estimate of the rotational shift between the first discrete curve and the second discrete curve. The final estimate may be used to perform curve matching.

Abstract: A frame buffer stores X pixels per line and Y lines and is read using a burst of B pixels. The un-rotated image is rotated by 90 degrees for display by writing and reading pixels from a line buffer. The line buffer stores a block of B*Y pixels. The frame buffer is logically divided into X/B blocks that are B pixels wide. Blocks are read from the frame buffer from the bottom line to the top with a burst of B pixels per line.

Pixels for a next block are written into the line buffer to locations vacated as pixels are read out. The increasing offset re-orders the pixels for the rotated display order.
