Abstract
Official abstract text for this publication.
A method, a device and a system for resizing an original depth frame into a resized depth frame. The method for resizing an original depth frame into a resized depth frame includes the steps of: obtaining two sub-pixel values from at least two pixels of the original depth frame, respectively; and storing the two sub-pixel values into corresponding two sub-pixels of one pixel of the resized depth frame, respectively.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for resizing an original depth frame into a resized depth frame, comprising steps of: retrieving one sub-pixel value from each of pixels of the original depth frame to obtain a plurality of retrieved sub-pixel values, wherein the sub-pixel values of the same pixel of the original depth frame are the same; and storing the three retrieved sub-pixel values into three sub-pixels of one pixel of the resized depth frame, respectively. 2. The method of claim 1 , wherein the original depth frame is a gray-level frame, and the sub-pixel values of each pixel of the gray-level frame are the same. 3. The method of claim 1 , wherein the size of the resized depth frame is ⅓ of the original depth frame along a column direction. 4. The method of claim 1 , wherein the size of the resized depth frame is ⅓ of the original depth frame along a row direction. 5. A device for resizing an original depth frame into a resized depth frame, comprising: a pixel retrieving unit for retrieving one sub-pixel value from each of pixels of the original depth frame to obtain a plurality of retrieved sub-pixel values, wherein the sub-pixel values of the same pixel of the original depth frame are the same; and a pixel storing unit for storing the three retrieved sub-pixel values into three sub-pixels of one pixel of the resized depth frame, respectively. 6. The device of claim 5 , wherein the original depth frame is a gray-level frame, and the sub-pixel values of each pixel of the gray-level frame are the same. 7. The device of claim 5 , wherein the size of the resized depth frame is ⅓ of the original depth frame along a column direction. 8. The device of claim 5 , wherein the size of the resized depth frame is ⅓ of the original depth frame along a row direction. 9. A system for resizing an original depth frame into a resized depth frame, comprising: a memory unit for storing the original depth frame; and a processing unit for retrieving one sub-pixel value from each of pixels of the original depth frame to obtain a plurality of retrieved sub-pixel values and storing the three retrieved sub-pixel values into three sub-pixels of one pixel of the resized depth frame, respectively, wherein the sub-pixel values of the same pixel of the original depth frame are the same. 10. The system of claim 9 , wherein the original depth frame is a gray-level frame, and the sub-pixel values of each pixel of the gray-level frame are the same. 11. The system of claim 9 , wherein the size of the resized depth frame is ⅓ of the original depth frame along a column direction. 12. The system of claim 9 , wherein the size of the resized depth frame is ⅓ of the original depth frame along a row direction.
