A target luma of the imaging device may be determined. A correspondence table may be obtained. The correspondence table may relate to a plurality of reference luma values and a plurality of groups of operation values of the set of exposure parameters, a group of operation values corresponding to a reference luma value. A reference luma value and a group of operation values of the set of exposure parameters may be identified based on the target luma and the correspondence table. An adjustment of at least one exposure parameter of the imaging device may be determined based on the identified group of operation values. The at least one exposure parameter of the imaging device may be adjusted based on the determined adjustment.

摘要： A neural network-based image processing method may include receiving, by a trained neural network, a first image including a first object, the first object being partially covered by a second object. The method may also include generating, by the trained neural network, a second image based on the first image. The second image is a representation of the first image with the second object substantially removed, and the first object is a human face.

摘要： A system includes a storage device storing a set of instructions and at least one processor in communication with the storage device. When executing the instructions, the at least one processor is configured to cause the system to obtain a first operation mode of the optical filter and determine a brightness value of visible light of ambient light. The at least one processor may also cause the system to obtain a brightness threshold related to the first operation mode, compare the brightness value of the visible light of the ambient light with the brightness threshold, and determine whether a switching condition is satisfied based on the comparison result. Upon the determination that the switching condition is satisfied, the at least one processor may further cause the system to switch the first operation mode of the optical filter to a second operation mode.
