This utility model discloses a black key for an electric piano and an electric piano, relating to the technical field of electric pianos. It is used to mount on a keyboard base and includes a key body and an outer cover. The key body includes a mounting base for connecting to the keyboard base, with a protrusion at the upper end of the mounting base. The outer cover is made of a translucent material and has an open bottom. The outer cover is fitted onto the protrusion. Through the cooperation of the outer cover and the key body, a jelly-like visual effect is produced, unlike existing technologies where the effect is directly derived from the keys themselves. This not only creates a more realistic visual effect but also eliminates the need to disassemble the entire electric piano when these keys with special visual effects show signs of aging such as yellowing after prolonged use, making maintenance convenient.

The application provides a cloud image efficient synthesis method, belonging to the field of image processing, comprising the following steps: calculating the edge distance transform of the mask of the foreground image to generate a multi-level boundary information graph; converting the background image and the foreground image to the Lab color space, and inputting the Lab channel, the mask and the multi-level boundary information graph into a generator network to output a preliminary fusion image in the Lab color space; using a brightness discriminator and a chroma discriminator to respectively judge the local texture consistency of the preliminary fusion image and a real fusion image in the L channel, and the global color harmony of the preliminary fusion image and the real fusion image in the a and b channels; performing the adversarial training of the generator network and the discriminator based on a total loss function until the network model converges, and using the converged generator network to generate a final fusion image. The application can guarantee the high realism and consistency of the fusion image in the details and the overall color tone.

The invention discloses a face video forgery detection method, which comprises the following steps of: 1, acquiring a data set, adopting a diffusion model as a core generation framework, extracting a stable and high-discrimination identity embedding vector from the input data set, and injecting the stable and high-discrimination identity embedding vector into a generation process of the diffusion model in a conditional constraint manner so as to generate a forgery data set; and 2, completing face counterfeiting detection by using the counterfeiting data set generated in the step 1 based on a fine-grained distribution migration strategy. The method provided by the invention is used for solving the technical problems of insufficient quality of forged data, lack of time sequence consistency, lack of identity feature modeling, poor cross-identity forging adaptability, insufficient sensitivity of a detection model to fine-grained artifacts and poor robustness.
