Calibration Approach

Colorimetric calibration computes the necessary color space transformation to map a camera's device-specific color space to a device-independent perceptual color space. Color calibration is most commonly performed by imaging a color rendition chart with a fixed number of color patches with known colorimetric values (e. g., CIE XYZ values). The color space transformation is estimated based on the correspondences between the camera's image and the chart's colors. We present a new approach to colorimetric calibration that does not require explicit color correspondences. Our approach computes a color space transformation by aligning the color distributions of the captured image to the known distribution of a calibration chart containing thousands of colors. We show that a histogram-based colorimetric calibration approach provides results that are onpar with the traditional patch-based method without the need to establish correspondences.

Tidak adanya nama jalan di lingkungan wilayah tempat tinggal menyebabkan warga RT 04-05 RW 16 Desa Ngenep, Kecamatan Karangploso, Kabupaten Malang kesulitan menemukan alamat tertentu. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk mendesain, membuat dan memasang Peta Situasi Wilayah di Desa Ngenep, Kecamatan Karangploso, Kabupaten Malang. Kegiatan dilaksanakan di RT 04-05 RW 16 Perumahan Tirtasani cluster Park Royal, mulai tanggal 24 April sampai 09 Nopember 2018. Metode PkM yang digunakan yaitu mendesain, membuat dan memasang Papan Peta Situasi Wilayah.  Rangka Peta Situasi didesain terbuat dari besi profil kotak 4x6 cm dan 3x3 cm berukuran 3x2 m. Pengerjaan rangka meliputi pemotongan, pengelasan, penggerindaan, pengecatan dan riveting. Dasar papan peta dibuat dari bahan lembaran alumnium ukuran 2x2 meter, sedangkan peta yang menggambarkan alamat rumah warga didesain dengan software desain grafis corel draw dan dicetak dengan outdor digital printing. Banner Peta Situasi ditempelkan pada lembaran alumninium dengan perekat lem, dan difinishing dengan rivet. Peta Situasi dipasang didepan pintu masuk RT 04-05 RW 16 (sekitar Pos Satpam) dan Taman Tengah, ditanam dengan kedalaman ± 50 cm dan dicor semen. Hasil PkM menunjukkan bahwa pengadaan Peta Situasi sangat bermanfaat dan warga RT 04-05 RW 16 Desa Ngenep, Kecamatan Karangploso, Kabupaten Malang, dimana warga merasa puas karena memiliki infrastruktur lingkungan yang baik dan lebih mudah untuk menemukan alamat di wilayah tersebut. Kata kata kunci: Desain dan pembuatan, peta situasi, Ngenep.

Digital printing has been playing a more and more important role in printing industry for its convenient production and quick turnaround. By experimental method, the differences of digital prints with different paper were detail analyzed, includes different base weight papers of the same category, and different categories papers with the same base weight. Results showed that the printing quality of offset paper with 120 g/m2base weight was better than that of 100 g/m2, and that printing quality of art paper was better than matt art paper with the same base weight. Other characteristics of different papers were investigated too. The method and conclusion provides in this paper would be helpful for choosing appropriate material for production activities.
