Description

In some remote sensing applications there is a need to interpolate the images. This paper explores the idea of using a super-resolution technique to generate images with a better resolution over a finer grid than the original sampling grid. The technique proposed here is based on POCS and DCT methods. The SR method is tested on Quickbird images and preliminary results have showed that good quality images are obtained with the proposed method. In order to allow quantitative analysis, the Universal Image Quality Index measure was also used.

في بعض تطبيقات الاستشعار عن بعد هناك حاجة لاستيفاء الصور. تستكشف هذه الورقة فكرة استخدام تقنية فائقة الدقة لإنشاء صور بدقة أفضل عبر شبكة أدق من شبكة أخذ العينات الأصلية. تعتمد التقنية المقترحة هنا على نقاط الاتصال وطرق دائرة الثقافة والسياحة. يتم اختبار طريقة SR على صور Quickbird وأظهرت النتائج الأولية أنه يتم الحصول على صور عالية الجودة باستخدام الطريقة المقترحة. من أجل السماح بالتحليل الكمي، تم أيضًا استخدام مقياس المؤشر العالمي لجودة الصورة.

Translated Description (French)

Dans certaines applications de détection à distance, il est nécessaire d'interpoler les images. Ce document explore l'idée d'utiliser une technique de super résolution pour générer des images avec une meilleure résolution sur une grille d'échantillonnage plus fine que la grille d'échantillonnage d'origine. La technique proposée ici est basée sur les COP ET les méthodes DCT. La méthode SR est testée sur les images Quickbird et les résultats préliminaires ont été obtenus à l'aide de la méthode proposée. Dans l'ordre de permettre une analyse quantitative, l'indice de qualité d'image universel a été mesuré, ce qui signifie qu'il a été utilisé.

Translated Description (Spanish)

In some remote sensing applications there is a need to interpolate the images. Este artículo explora la idea de usar una técnica de super-resolución para generar imágenes con una mejor resolución a través de una rejilla más fina que la rejilla de muestreo original. The technique proposed here is based on POCS and DCT methods. The SR method is tested on Quickbird images and preliminary results have showed that good quality images are obtained with the proposed method. In order to allow quantitative analysis, the Universal Image Quality Index measure was also used.
