Signal noise reduction processing method, device and equipment and storage medium

Abstract

The invention discloses a signal noise reduction processing method, device and equipment and a storage medium, and relates to the field of computers. The method comprises the following steps: acquiring a to-be-denoised signal curve, wherein the signal curve is generated based on motion data; inputting the to-be-denoised signal curve into a pre-trained neural network model to obtain a denoising parameter corresponding to each data in the to-be-denoised signal curve, and obtaining a pre-denoised signal curve according to the denoising parameter corresponding to each data; and smoothing the pre-denoised signal curve to obtain a target signal curve. According to the invention, the curve with the noise reduction signal is subjected to noise reduction processing through the pre-trained neural network model and then is subjected to smoothing processing, so that the target signal curve obtained through the method not only can reserve details of a non-noise signal, but also can effectively smooth noise so as to solve the problem that under the condition of relatively large signal glitch, the burr smooth curve cannot be effectively filtered out by directly performing smoothing processing.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technologies, and in particular to a signal noise reduction processing method, device, device, and storage medium. Background technique [0002] Game animation designers need to remove the jitter in game animation in Maya or other animation editing software. The animation is controlled by the translation or rotation of the character's joints. When the animation is played, the positions of the joints are updated in real time according to the translation or rotation data of these joints, so that the whole character can move. Animators often need to denoise these curves to smooth out the movement of the entire character. If the rotation curve of the joint is very jittery, it will cause the movement of the whole character to be very jittery, which will greatly affect the game experience. [0003] Usually, using an adaptive filter to smooth the curve can remove the jitter part of t...
