This post is pending Intro: faceswap & deepfake Face swap refers to an activity in which a person's face is swapped with the face of another person. Deepface = deeplearning + fake. Deepfake is an advanced technology, but 96% ò Deepfakes videos have triolous content. Deepfake also targets political purposes, fraud and market manipulation. Traditional swap face - using opencv-dlib Facial landmark Detection Facial landmarks are used to localize and represent salient regions of the face. The pre-trained facial landmark detector inside the dlib library is used to estimate the location of 68(x,y)-coordinates that map to facial structures on the face. Each frame of the animation shows a Delaunay trianulation of the four points. Halfway through, the trianglulating edge flips showing that the Delaunay trianglulation maximizes the minimum angle, not the edge-length of the triangles. The final steps of face alignment to to consider corresponding triangles between the source fac...

  Errichto gave Monogon the following challenge in order to intimidate him from taking his top contributor spot on Codeforces. In a Tic-Tac-Toe grid, there are  n n  rows and  n n  columns. Each cell of the grid is either empty or contains a token. There are two types of tokens:  X  and  O . If there exist three tokens of the same type consecutive in a row or column, it is a winning configuration. Otherwise, it is a draw configuration. The patterns in the first row are winning configurations. The patterns in the second row are draw configurations. In an operation, you can change an  X  to an  O , or an  O  to an  X . Let  k k  denote the total number of tokens in the grid. Your task is to make the grid a  draw  in at most  ⌊ k 3 ⌋ ⌊ k 3 ⌋  (rounding down) operations. You are  not required  to minimize the number of operations. Input The first line contains a single integer ...
