Item Cast-Shadow Removal for Cooperative Adaptive Appearance Manipulation(The Eurographics Association, 2022) Uesaka, Shoko; Amano, Toshiyuki; Hideaki Uchiyama; Jean-Marie NormandWe propose a framework to suppress over-illumination at the overlapping area created by cooperative adaptive appearance manipulation with independently working two projector-camera systems. The proposed method estimates projection overlapping in each projector-camera unit with neither geometrical mapping nor projection image sharing. Then, the method suppresses the projection illumination of the overlapping area by compensated reflectance estimation. Experimental results using two projector-camera systems confirm that the proposed method correctly detects overlapping areas adaptively and removes cast shadows that cause uneven illumination owing to cooperative appearance manipulation of a moving 3D target.Item Gaze Guidance in the Real-world by Changing Color Saturation of Objects(The Eurographics Association, 2022) Miyamoto, Junpei; Koike, Hideki; Amano, Toshiyuki; Hideaki Uchiyama; Jean-Marie NormandIn this study, we propose a method for real-world gaze guidance by projecting an image onto a real-world object and changing its appearance based on visual saliency. In the proposed method, an image of the object is first acquired. Next, the image is changed such that the visual prominence of the object is increased and the image is changed so that the visual prominence of other parts of the object is decreased. Finally, the modified image is re-projected onto the object itself. Consequently, the object's appearance and visual prominence are altered, and the user's gaze is focused on the desired object. In this study, we propose an image processing method that changes the saturation of an object. We call this the "saturation filter." A coaxial projector-camera system was used to apply the proposed gaze guidance method proposed in this study to a 3D object. The coaxial projector-camera system does not need to be recalibrated when an object moves. In this study, two experiments were conducted to verify the effectiveness of the proposed method in guiding a viewer's gaze. As a result, it was confirmed that the proposed method can achieve the effect of gaze guidance.
