Image sequence enhancement system and method
Motion picture scenes to be colorized are broken into separate elements, backgrounds/sets or motion/onscreen-action. Background and motion elements are combined separately into single frame representations of multiple frames which becomes a visual reference database that includes data for all frame offsets used later for the computer controlled application of masks within a sequence of frames. Each pixel address within the database corresponds to a mask/lookup table address within the digital frame and X, Y, Z location of subsequent frames. Masks are applied to subsequent frames of motion objects based on various differentiating image processing methods, including automated mask fitting of all masks or single masks in an entire frame, bezier and polygon tracing of selected regions with edge detected shaping and operator directed detection of subsequent regions. The gray scale actively determines the mask and corresponding color lookup that is applied in a keying fashion within regions of interest.
1. A method of creating a visual reference database comprising: at least one computer implementing the following step of:
associating a plurality of images comprising common background elements;
obtaining a composite background comprising said plurality of images wherein said composite background excludes a set of motion objects that move in relation to said common background elements;
associating a first mask with a motion object selected from said set of motion objects in a first image selected from said plurality of images;
accessing a mask value associated with said first mask in said first image wherein said mask value is stored in a visual reference database;
accessing a camera value associated with said first image wherein said camera value is stored in said visual reference database;
copying said mask value associated with said first mask to create a second mask value associated with a second mask and further associated with a second image selected from said plurality of images;
moving said second mask value to a location of said motion object in said second image;
reshaping said second mask value to fit said motion object in said second image based on said camera value; and,
storing said second mask value in said visual reference database.
2. The method of claim 1 further comprising:
accessing a descriptive text value associated with said first image in said visual reference database.
3. The method of claim 1 wherein said accessing a mask value comprises:
accessing a mask location associated with said first image in said visual reference database;
accessing a mask shape associated with said first image in said visual reference database.
4. The method of claim 1 wherein said accessing a camera value comprises:
accessing a camera angle value associated with said first image in said visual reference database;
accessing a camera location value associated with said first image in said visual reference database;
accessing a camera focal length value associated with said first image in said visual reference database;
accessing a zoom value associated with said first image in said visual reference database.
