Finger print collecting and joining method supporting arbitrary directional rolling

The invention relates to a method for collecting and splicing a fingerprint, which can support the rolling in any direction and is a method for identifying and processing a fingerprint picture. The method applies a fingerprint collecting system which is composed of a fingerprint collector, a computer and a fingerprint collecting and splicing program, and comprises the steps of starting the initialization of the fingerprint collecting and splicing program, initial collecting, formal collecting, determining a fingerprint area of a current frame, updating a spliced picture, determining a fingerprint area of the spliced picture, generating a picture with splicing effects and displaying the picture with splicing effects. The method adopts a picture splicing method with a background picture as a reference and eliminates the restriction of the rolling direction during a fingerprint collecting process by rolling so that a complete fingerprint splicing picture can be formed with a finger to roll on a fingerprint collecting surface in any direction. In addition, the method also applies the weighted average method to process edges of the fingerprint splicing picture to ensure that the spliced fingerprint picture can be more natural and smooth.

Voice-driven 3D virtual human expression voice and picture synchronization method and system based on deep learning

The invention relates to a voice-driven 3D virtual human expression voice and picture synchronization method and system based on deep learning. The method comprises the following steps: extracting a logarithm amplitude spectrum in a voice signal as a voice signal characteristic; inputting the voice signal characteristic into a trained parameter prediction model which outputs an expression parameter value, wherein the parameter prediction model is a neural network model obtained by training a natural label pair relationship between a voice signal and an image signal in the video data; filteringthe expression parameter value output by the parameter prediction model; and performing image rendering of a 3D figure model by using the filtered expression parameter value to realize 3D virtual figure expression sound and picture synchronization. The system comprises a video analysis module, a parameter extraction module, a voice synthesis module, a voice signal processing module, a parameter prediction module, a parameter filtering module and a rendering module. According to the invention, the mouth lip effect of a virtual person is improved by learning a large amount of face video data such that the mouth lip effect is more natural and human-like.
