The Video Enhancement tool is used to improve video image quality before running the 2D inference, lens calibration, or chessboard calibration processes.

The Video Enhancement tool allows you to improve video quality before processing data, which can be especially useful for calibration under challenging lighting conditions. Changes made using this tool are previewed for the loaded 2D views, and any enhancements are applied before running the 2D inference, lens calibration, or chessboard calibration processes. Therefore, what you see in the 2D views is how the video data will be processed. ### **All Views** Apply the selected enhancements to all camera views. Alternatively, select an individual camera from the dropdown menu to apply individual camera enhancements. ### **Brightness** Increase or decrease the brightness of the videos. Default (no enhancement) is 0. ### **Contrast** Increase the contrast of the videos. Default (no enhancement) is 1.00. ### **White Balance** Adjust the white balance of the videos by performing a color correction using a baseline white color. Enable White Balance by selecting the square, and click on the white rectangle to open the color picker. You can select a specific color, input color values, or use the Pick Screen Color option to select a pixel from within your loaded videos of a white surface such as the chessboard. ### **Blue Mask** Shows which pixels are detected as blue by the chessboard calibration algorithm. This is useful for adjusting your videos before processing a chessboard calibration to ensure the blue squares are detected. The global coordinate system origin is defined at the intersection of the blue squares, which must be detected in order to define the origin. ### **Reset** Reset all changes to default values, removing any video enhancements. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.theiamarkerless.com/apollo-v2024/theia3d-documentation/theia3d-dropdown-menus/tools-menu/enhance-videos.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
