| 28 | 6 | Chung Hsi LIN | |
| 29 | 18 | Mitsuki EIKI | Our project aims to create a single, large, seamless image on a flat-screen display using two projectors and two laptops. The projectors are aligned to overlap on the screen, with pictures resized to utilize the full resolution of both devices. We employ techniques such as gamma correction, alpha blending, and intensity modification to enhance image quality and achieve smooth blending in the overlapping region. |

| 37 | 11 | Chung Hsi LIN | Problem and Solution: |
| 38 | |||
| 39 | 12 | Chung Hsi LIN | The general idea of alpha blending extends from techniques used in movie rendering, or in this case, overlapping projection. The problem with overlapping projection is that the overlapping area is considered as collisions where such conflicts need to be resolved. In the case of computer rendering, the most common method is referred as the painter's method, which would only render one of the overlapping projections. Alpha blending is a proposed solution to would blend both projections. The problem of blending is the stacking luminosity of the two projections. Alpha blending describes the technique to find a alpha coefficient to adjust the luminosity of both projects under the overlapping area. |
