Abstract

Kerangka  umum  perbaikan  citra  berdasarkan  histogram  equalization  telah  banyak digunakan peneliti terutama untuk meningkatkan kontras citra. Namun dengan metode ini menghasilkan nilai kontras yang berlebihan sehingga menampilkan bentuk yang tidak alami serta munculnya cacat visual. Dalam tulisan ini kami menggunakan metode yang disebut Probability  Distribution  Histogram  Equalization  (PDHE).  Mula-mula  citra dihitung nilai Probability Density Function (PDF) hasil yang didapat untuk mencari nilai Cumulative Distribution Function (CDF). Selanjutnya hasil yang didapatkan digunakan untuk nilai acuan dalam alih ragam point-wise citra keabuan. Evaluasi ujicoba yang telah dilakukan, nilai optimal keluaran citra hasil histogram equalization dengan menggunakan ukuran window [35 35] dengan SNR = 1.52 dan waktu proses yang dibutuhkan  3.0677 detik. Metode ini menghasilkan  keluaran  citra yang  lebih  baik secara visual bila dibandingkan dengan metode histogram equalization klasik. Sebagai pembanding, diperlihatkan hasil histogram dan tampilan citra dengan metode spesifikasi histogram dan metode lokal histogram. Kata kunci: histogram equalization, PDHE, spesifikasi dan lokal histogram, SNR

Abstract

PT. XYZ is a company engaged in the sport shoe with the marketing areas inside and outside the country. One of the products produced by PT. XYZ is running shoes. The problems faced by the company is not achieving the production targets because many value-added activity not belonging to the waste (waste). For that use lean manufacturing approach to eliminate waste that occurs on in the production line at PT. XYZ. Lean manufacturing methods used is values stream mapping (VSM) to analyze the dominant waste in the manufacturing process. Based on the analysis we found three recommendations for improvement, namely the use of a forklift, the addition operator and addition of machine. Results of evaluation of recommendation is decreased production lead time equal to 8610.62 sec, increasing the value of Process Cycle Efficiency of 21.08%.
