At no other time in human history have the influence and impact of image processing on modern society, science, and technology been so explosive. Image processing has become a critical component in contemporary science and technology and has many important applications. This book develops the mathematical foundation of modern image processing and low-level computer vision, and presents a general framework from the analysis of image structures and patterns to their processing. The core mathematical and computational ingredients of several important image processing tasks are investigated. The book bridges contemporary mathematics with state-of-the-art methodologies in modern image processing while organizing the vast contemporary literature into a coherent and logical structure.

Flotasi merupakan proses pengambilan mineral berharga dari pengotornya. Flotasi kolom digunakan untuk pengambilan mineral berharga dengan nilai kadar lebih tinggi dibandingkan flotasi konvensional. Dalam rangka menentukan efisiensi proses flotasi, diperlukan proses monitoring. Desain kolom dibuat dalam skala laboratorium dengan tinggi 120 cm dan diameter 5 cm. Proses monitoring dilakukan dengan kamera berkecepatan 240 fps. Kemudian dilakukan image processing dengan Picsara dan MatLab. Bijih yang digunakan adalah ZnS dengan variasi ukuran partikel 163, 127 89.5, dan 74 mikron. Percobaan dilakukan dengan injeksi udara 2, 2.5, 3, 3.5 dan 4 L/menit. Hasil penelitian menunjukan bahwa proses monitoring mampu meningkatkan efisiensi dari nilai recovery pada proses flotasi. ...... Flotation is the process of taking valuable minerals from its impurities. Flotation columns are used for the retrieval of valuable minerals with higher grade values than conventional flotation. In order to determine the efficiency of the flotation process, a monitoring process is required. Column design is made in laboratory scale with height 120 cm and diameter 5 cm. Monitoring process is done with camera speed 240 fps. Then image processing is done with Picsara and MatLab. The ore used is ZnS with particle size variations of 163, 127, 89.5 and 74 micron. The experiments were performed with 2, 2.5, 3, 3.5 and 4 L min of air injections. The results showed that the monitoring process can improve the efficiency of the recovery value in the flotation process.
