The present disclosure relates to a hand-gesture-based interaction method and apparatus, and a client. The method includes: in a live stream process of one network live stream, when a function of playback of a hand gesture animation is in an activated state, a client of an anchor user recognizes a hand gesture of the anchor user. When a hand gesture category matches a preset category of the hand gesture animation, the client of the anchor user plays back the hand gesture animation in a first area corresponding to a hand gesture position, and transmits a first content to a client of a viewing user through a first server. The client of the viewing user, based on the first content, plays back the hand gesture animation in a second area corresponding to the hand gesture position, and detects a trigger operation on the second area.

Hand-gesture-based interaction method and apparatus, and client

An information display method and apparatus, and an electronic device are provided. The method includes: receiving an instruction for displaying a page for instant messaging; displaying, in response to the instruction, a display page for the instant messaging, where the display page includes a first display area and a second display area; and displaying contact information in the first display area and displaying filtered information in the second display area, where the contact information includes an identifier of at least one contact and interaction information with the contact, the filtered information includes a filter identifier and information of a message corresponding to the filter identifier; and a message corresponding to a filter identifier is obtained by performing filtering on messages to at least one contact under a preset filtering condition corresponding to the filter identifier.

Information display method and apparatus, and electronic device

An image processing method and corresponding system operate by obtaining a first image and generating a first histogram information based on the first image. The method then obtains a cumulative-distribution-function (CDF) curve according to the first histogram information and generates an adaptive curve according to a high-contrast curve and a low-contrast curve. Finally, the method uses the adaptive curve to adjust the CDF curve to generate a mapping curve, and adjusts the first image by using the mapping curve to generate a second image with contrast enhancement effect.

Methods for enhancing image contrast and related image processing systems thereof

An image fusion method for removing ghost artifacts is provided. The method includes: determining a first fusion weight of a reference pixel in a reference frame, wherein the coordinates of the reference pixel are the same as the coordinates of one of input pixels included in an input frame; determining a reference brightness parameter according to values of all channels of the reference pixel; determining an input brightness parameter according to values of all channels of the input pixel; determining a ghost weight according to an amount that the brightness parameter ratio of the input brightness parameter and the reference brightness parameter deviates from a reasonable range; determining a fusion weight according to the first fusion weight and the ghost weight; and fusing the reference pixel with the input pixel according to the fusion weight to generate a fused pixel in a fused frame.

Image fusion method and device for removing ghost artifacts

Methods for enhancing image contrast applied to an image processing system are provided. The method includes the steps of: obtaining a first image; generating a first histogram information based on the first image; obtaining, a first parameter and a second parameter of the first image based on the first histogram information, wherein the first parameter is related to the number of homogeneous regions of the first image and the second parameter is related to an average luminance information of the first image; performing a weighted calculation based on the first parameter and the second parameter to determine a restriction parameter; performing a contrast limited histogram equalization processing on the first histogram information using the restriction parameter to generate a second histogram information; and adjusting the first image based on the second histogram information and a mapping curve to generate a second image with contrast enhancement effect.
