... As is known, digital radiographic images have weaknesses where the resulting image has low resolution and qualiaty for further interpretation. Further interpretation can be done by doing image processing of digital radiographic images because it can increase the visibility of details in the image [12]. ...
... Hal ini menyebabkan proses interpretasi citra kurang maksimal sehingga untuk lebih menggali informasi lebih jauh perlu dilakukan image processing. Hal ini sangat penting untuk radiografi digital karena dapat meningkatkan visibilitas detail dalam citra radiografi digital [11]. Selain itu Image processing dilakukan untuk memperbaiki kesalahan data sinyal gambar yang terjadi akibat transmisi selama akuisisi sinyal, serta untuk meningkatkan kualitas penampakan gambar agar lebih mudah diinterpretasi oleh sistem penglihatan manusia baik dengan melakukan manipulasi dan analisa gambar [2]. ...
IMAGE ENHANCEMENT CITRA DIGITAL SHORT PIN PWR FUEL BERISI PELET UO2 ALAM PASCA UJI RADIOGRAFI SINAR-X MENGGUNAKAN PROGRAM IMAGEJ. Pengujian tak merusak menggunakan radiografi sinar-X digital merupakan salah satu rangkaian penting dalam evaluasi unjuk kerja bahan dan bahan bakar nuklir. Image enhancement atau peningkatan kualitas citra sangat dibutuhkan untuk analisis lanjutan terhadap citra hasil radiografi sinar-x digital yang cenderung memiliki resolusi lebih rendah. Proses image enhancement pada citra radiografi sinar-x digital dilakukan untuk memberikan citra yang lebih mudah diinterpretasi sehingga data yang dihasilkan dapat digunakan sebagai dasar evaluasi unjuk kerja setelah proses iradiasi. Pengujian menggunakan radiografi sinar-X digital dilakukan pada short pin PWR fuel berisi pelet UO2 dilakukan pada jarak 40 cm terhadap detektor dengan parameter tegangan dan arus berturut-turut sebesar 120 kV dan 1000 μA. Selanjutnya dilakukan image enhancement terhadap citra digital menggunakan ImageJ yang meliputi proses penyelarasan terhadap kontras citra, edge enhancement, pengolahan histogram gray value, dan penyesuaian warna citra. Data uji disesuaikan dengan informasi yang harus dicapai dari pengujian radiografi sinar-x digital short pin PWR fuel berisi pelet UO2. Informasi ini dapat berupa data dimensi, batas antar pelet, dan histogram yang menggambarkan adanya perbedaan material atau perbedaan ketebalan. Informasi ini selanjutnya dapat digunakan sebagai input data dalam pemetaan konsep image enhancement short pin PWR fuel berisi pelet UO2. Output citra yang dihasilkan dari proses image enhancement memiliki resolusi dan kualitas citra yang lebih baik untuk memudahkan dalam proses analisis dan interpretasi serta dapat dijadikan metode baku dalam melakukan image enhancement citra radiografi sinar-x digital short pin PWR fuel berisi pelet UO2 pasca iradiasi.

... CNL has developed a prototype image processing software, which is constantly being upgraded and improved. This software is used not only for processing of radiographic images, but also as a test bed for development and evaluation of new image processing algorithms [1]. ...
... In 2010, CNL started development of an image processing software (called CNL Image Processing Tool, or IPT), which was intended to be used for implementation and testing of new image processing algorithms. At the current stage, all basic editing and image manipulation functions are implemented [1], and work is underway on the development of advanced image processing algorithms and their implementation and testing. The main window of the software has three regions: menus, control buttons, and display area (see Figure 1). ...
