Abstract

Citra digital dapat disajikan dalam bentuk graf atau graf grid. Segmentasi secara luas digunakan dalam visi komputer. Segmentasi citra dilakukan dalam berbagai pendekatan, antara lain: Pendekatan daerah berkembang, pendekatan batas, pendekatan graf. Masalah yang akan dipelajari dalam tulisan ini adalah apakah ada perbedaan bentuk segmen-segmen jika citra yang diubah dalam graf grid, graf triangular grid, atau graf super grid? Salah satu pendekatan segmentasi citra adalah penggunaan pohon perentang minimum. Caranya adalah sisi-sisi pohon perentang minimum suatu graf yang dibentuk dari citra yang bobot sisinya lebih besar dari ambang batas dihapus. Sehingga terbentuk sub-sub pohon yang merupakan titik-titiknya pembentuk segmen-segmen dari citra. Dari hasil penelitian diperoleh pertama, segmentasi dengan pohon perentang minimum dengan ambang batas (s + ) cocok untuk citra digital yang diubah ke graf grid. Kedua, segmentasi dengan pohon perentang minimum dengan ambang batas (s + ) cocok untuk citra digital yang diubah ke graf triangular grid. Ketiga, segmentasi dengan pohon perentang minimum dengan ambang batas (s + ) tidak cocok untuk citra digital yang diubah ke graf super grid.

Abstract

The control device in an auto-navigation car is a computer assisted by two cameras on the front of the car to determine the three-dimensional coordinates of all pixels of the digital image captured by the camera from frame to frame. So that the computer will be able to determine where the streets are flat or potholes. The purpose of this research is to create a program code that is able to determine the disparity from one frame to the next. With the help of recordings from two cameras, the disparity of any object captured on the two cameras will be calculated for each pixel. This data is used to compare the accuracy of the methods developed in this study. We use a program code developed to calculate the disparity of each frame in the video. The model developed in this study still needs to be studied in order to find a better method.
