| Abstract (English): |
Currently, an approach involving a coder with a combined structure for compressing images combining several different coders, the system for connecting them to various bit planes, and the control system for these connections have not been studied. Thus, there is a need to develop a structure and study the effectiveness of a combined codec for compressing images of various types without loss in the spatial domain based on arithmetic and (Run-Length Encoding) RLE-coding algorithms. The essence of separate effective coding is to use independent coders of the same type or one coder connected to the planes alternately in order to compress the higher and lower bit planes of the image or their combinations. In this paper, the results of studying the effectiveness of using a combination of arithmetic and RLE coding for several types of images are presented. As a result of developing this structure, the effectiveness of combined coding for compressing the differences in the channels of hyperspectral images (HSI) has been established, as hyperspectral images consist of multi-spectral bands, instead of just the typical three bands (RGB) or (YCbCr) found in regular images. Where, each pixel in a hyperspectral image represents the entire spectrum of light reflected by the object or scene at that particular location. [ABSTRACT FROM AUTHOR] |
| Abstract (Arabic): |
المقال يركز على تطوير وفعالية كوديك مشترك لضغط مستويات البت في الصور الرمادية، وخاصة الصور الطيفية العالية، باستخدام خوارزميات الترميز الحسابي وترميز طول التشغيل (RLE). يقترح المؤلفون هيكلًا يستخدم ترميزًا فعالًا منفصلًا لمستويات البت العالية والمنخفضة، مما يظهر أن كوديكات مختلفة يمكن أن تحقق نسب ضغط أعلى لأنواع مختلفة من الصور. تكشف الدراسة أن الترميز المشترك يعزز بشكل كبير كفاءة الضغط، خاصة بالنسبة للصور الطيفية العالية، من خلال تحسين استخدام تقنيات الترميز المختلفة لمستويات البت المختلفة. تشير النتائج إلى أن هذه الطريقة يمكن أن تحسن نسب الضغط بمعدل يتراوح بين 1.4 إلى 3.1 مرة مقارنة بالطرق التقليدية.
