Geometric Transformations of BDD Encoded Image
نویسندگان
چکیده
Binary Decision Diagram (BDD) has been shown to be applicable in image coding. A technique presented in this paper extends the functionality of BDD in image coding to cover major geometric transformations of image such as translation, rotations, scaling and shearing. By introducing the concept of transition branch, nonuniform and uniform translation of image by a given displacement could be obtained using only exclusive-or operation. Based on the translation, we show that image rotation, scaling and shearing could be achieved.

متن کاملBdd Minimization by Linear Transformations
Binary Decision Diagrams (BDDs) are a powerful tool and are frequently used in many applications in VLSI CAD, like synthesis and veriication. Unfortunately, BDDs are very sensitive to the variable ordering and their size often becomes infeasible. Recently, a new approach for BDD minimization based on linear transformations, i.e. a special type of spectral techniques, has been proposed. In this ...
متن کاملModularity as a fish (Xenotoca eiseni) views it: conjoining geometric and nongeometric information for spatial reorientation.
When disoriented in a closed rectangular tank, fish (Xenotoca eiseni) reoriented in accord with the large-scale shape of the environment, but they were also able to conjoin geometric information with nongeometric properties such as the color of a wall or the features provided by panels located at the corners of the tank. Fish encoded geometric information even when featural information sufficed...
