Klasifikasi Jenis Buah Jambu Biji Menggunakan Algoritma Principal Component Analysis dan K-Nearest Neighbor

The maturity level of guava fruit can be determined by looking at various factors. Shape is one the factors that play a role in identifying certain objects. classification seen from shape, texture and color. shape quite diverse ranging round (Round shape) to oval (Pear shape). So Matlab application was built determine type based on its color, texture. K-Nearest Neighbor classify objects learning data closest object so results more accurate. Principal Component Analysis (PCA) statistical technique for simplifying many-dimensional sets into lower dimensions (extration features). combination with produces fairly high accuracy determining using total 45 images divided two including training 36 test 9 data.
