|Light field reconstruction from images captured by focal plane sweeping can achieve high lateral resolution comparable to the modern camera sensor. However, the severe defocus noise and the low depth resolution limit its applications. In this work, we analyze the defocus noise in the focal plane sweeping based light field reconstruction technique, and propose a method to reduce the defocus noise.|
- Camera Simulator based on light field propagation
We made a virtual camera simulator based on the light filed transformation. The 3D object center is supposed be at the reference focal plane, the light field of the object at the reference plane thus can be calculated. By propagating the light field with the free space transform matrix with the object distance, lens transform matrix, free space transform matrix with the image distance, the light field at the sensor can be obtained. This simulator is useful for techniques based on photographic images, such as coded aperture, light field reconstruction from photographic images.
