Object segmentation and tracking are improved by including directional information to guide the placement of an active contour (i.e., the elastic curve or ‘snake’) in estimating the object boundary. In estimating an object boundary the active contour deforms from an initial shape to adjust to image features using an energy minimizing function. The function is guided by external constraint forces and image forces to achieve a minimal total energy of the active contour. Both gradient strength and gradient direction of the image are analyzed in minimizing contour energy for an active contour model.

Methods for vessel segmentation and tracking using 7D MRI flow image data incorporate information from the velocity field and the magnitude. A vessel tracking methods selects a time containing sufficient blood flow through a vessel, uses the magnitude image to determine the vessel boundary and uses the velocity image to define the vessel direction.

With the 7D data, the vector field is available from the flow data, from the time point at which maximal flow occurs in the vessel of interest.

Some embodiments of the invention provide a method for specifying a bit allocation for encoding a set of images in a sequence of video images. The method computes a masking value for one or more images. The method computes a bit allocation for a current image based on the computed masking value of one or more images. In some embodiments, the method further ascertains a total number of bits used for images that have been already encoded before computing the bit allocation. The computed bit allocation for the current image is also based on the total number of bits used in some embodiments of the invention.

In some embodiments, the sequence of frames is divided into a set of blocks, where each block has (1) a size and (2) a bit allocation. Some embodiments dynamically adjust the size of the blocks during the encoding operation. In some embodiments, unused bits allocated to a first block are rolled over to a second block. In other embodiments, only some of the unused bits are rolled over to the second block.
