Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for editing shadows in digital images. In particular, in some embodiments, the disclosed systems determine, utilizing a lighting estimation network, an environment map for a digital image, the environment map comprising a dominant light. In addition, in some embodiments, the disclosed systems generate, utilizing a lighting diffusion network, a diffused image from the digital image, the diffused image comprising smoothed shading. Moreover, in some embodiments, the disclosed systems generate, utilizing a shadow synthesis network, a shadowed image from the diffused image and a modified environment map comprising a modified dominant light. Furthermore, in some embodiments, the disclosed systems generate, from the diffused image and the shadowed image, a modified digital image comprising an edited shadow.

Abstract: A thin client computer comprises a machine body and a base. The machine body has a motherboard mounted therein. The motherboard has a base connector on one side for exposing to the outside of the machine body. The base has an opposite connector for coupling with the base connector of the motherboard and several peripheral connection ports for coupling with several peripherals. The machine body can be coupled with the opposite connector of the base via the base connector so that the peripherals can be coupled with the peripheral connection ports of the base for further providing the machine body with more available functions.

Abstract: A multi-functional portable information learning device comprises a seat, a machine body, a circuit control unit. The seat is installed with a receptacle for being connected to a connector at a bottom of the machine body. The tilt portion receptacle is connected to a connecting seat. The connecting seat is connected to a computer through a universal series bus transmission line. The machine body is installed with a operation key set, a lateral key set, a liquid crystal window, a multimedia memory extension slot. A circuit control unit is installed within the machine body. The circuit control unit is connected to a connector, a liquid crystal window, a operation key set, a lateral key set, and the multimedia memory extension slot. Thereby, the voice and text are displayed synchronously and text or music is uploaded or downloaded or synchronously for enhancing language learning effect and extending memory.
