Abstract AR
تبنينا طريقة القيمة الوسطى لإزالة الضوضاء من الصور المضطربة.
طريقتان مقترحة لإزالة التشوه من الصور و ھي (Pentagonal-Hexagonal mask and Scan Window Mask) الدراسة تضمنت مرشح القيمة الوسطى المحور، التحوير أخذ بنظر الاعتبار أعطاء دقة نتائج أكثر.
طريقة (Pentagonal-Hexagonal mask) أعطت نتائج أفضل مقارنة مع مرشح القيمة الوسطى التقليدي و الطريقة المقترحة الأخرى Scan Window Mask و لكن تستغرق وقت أطول.
أحيانا طريقة cross 3x3 تتفوق على طريقة Pentagonal-Hexagonal بقليل في إزالة الضوضاء من النوع line.
أما طريقةScan Window Mask أعطت نتائج عيا نية أفضل في إزالة الضوضاء من النوع line أيضا تستغرق وقت أطول.
Abstract EN
Median filter is adopted to match the noise statistics of the degradation seeking good quality smoothing images.
Two methods are suggested in this paper (Pentagonal-Hexagonal mask and Scan Window Mask), the study involved modified median filter for improving noise suppression, the modification is considered toward more reliable results.
Modification median filter (Pentagonal-Hexagonal mask) was found gave better results (qualitatively and quantitatively) than classical median filters and another suggested method (Scan Window Mask), but this will be on the account of the time required.
But sometimes when the noise is line type the cross 3 x 3 filter preferred to another one Pentagonal-Hexagonal with few variation.
Scan Window Mask gave better results qualitatively when removing line noise than another filters, also will be on the account of the time required.
