Abstract
To encode an arbitrary shape, a processor is configured to generate a rectangular block of transform coefficients by applying a discrete separable unitary transform to a rectangular boundary block of a video object. The boundary block includes a masked pixel and an unmasked pixel, the transform coefficients include a number of zero-valued transform coefficients greater than or equal to a number of masked pixels, and the transform coefficients include at least one non-zero-valued transform coefficient. The processor is also configured to generate an encoded output by compressing only the non-zero-valued transform coefficients.
