Perkalian Citra Perkalian citra ini merupakan perkalian citra A dengan scalar C yang akan menghasilkan citra baru berupa B yang intensitasnya lebih terang dari semua. 1. Source Code nya sebagai berikut : A = double (imread (‘cameraman.tif’)); [r c] = size (A); WitrynaAn indexed image can be logical, uint8, double, or single. An intensity image can be logical, uint8, double, single, int16, or uint16. The input image must be nonsparse. If your image is int16 or single, the CData in the resulting image object will be double. For all other classes, the CData matches the input image class..
