Abstract: Provided are a method of recognizing a fingerprint and a device including the same. The method of recognizing a fingerprint includes obtaining a fingerprint image from a fingerprint sensor, determining whether a pixel in the fingerprint image is defective based on a dispersion value of the pixel with respect to time, in response to determining that the pixel is defective, generating an interpolated pixel value of the pixel by performing interpolation on a first pixel value of the pixel based on a second pixel value of another pixel different from the pixel, and correcting the fingerprint image based on the interpolated pixel value.

Abstract: A method and an apparatus for adjusting a pose in a face image are provided. The method of adjusting a pose in a face image involves detecting two-dimensional (2D) landmarks from a 2D face image, positioning three-dimensional (3D) landmarks in a 3D face model by determining an initial pose of the 3D face model based on the 2D landmarks, updating the 3D landmarks by iteratively adjusting a pose and a shape of the 3D face model, and adjusting a pose in the 2D face image based on the updated 3D landmarks.

Abstract: A surface treatment apparatus and a surface treatment system having the same are disclosed. The surface treatment apparatus includes a process chamber in which the surface treatment process is conducted, a plasma generator for generating process radicals as a plasma state for the surface treatment process, the plasma generator being positioned outside of the process chamber and connected to the process chamber by a supply duct, a heat exchanger arranged on the supply duct and cooling down temperature of the process radicals passing through the supply duct and a flow controller controlling the process radicals to flow out of the process chamber. The flow controller is connected to a discharge duct through which the process radicals are discharged outside the process chamber. The plasma surface treatment process is conducted to the package structure having minute mounting gap without the damages to the IC chip and the board.
