A method for detecting a facial area on a color image includes (a) placing a search window on the color image, (b) determining if a center pixel of the search window is a skin color pixel, indicating that the search window is a possible facial area candidate, (c) applying a 3-rectangle filter to the search window to determine if the search window is a possible facial area candidate, (d) applying a 4-rectangle filter to the search window to determine if the search window is a possible facial area candidate, (e) if steps (b), (c), (d) all determine that the search window is a possible facial area candidate, applying an AdaBoost filter to the search window to determine if the search window is a facial area candidate, and (f) if step (e) determines that the search window is a facial area candidate, saving the location of the search window.

Face detection on mobile devices

A method is provided for cloning a facial feature template image into an original image including a face to form a new image. The method includes detecting the face and facial features in the original image, reducing the original and the template images, cloning the reduced template image into the reduced original image to form a new image, enlarging the new image, and displaying the enlarged new image. The method may use Poisson cloning where a resulting system of linear equations is solved by applying a Thomas algorithm to determine an initial solution and applying a Conjugate Gradient algorithm using the initial solution to determine a final solution to the system of linear equations.
