Abstract

Urban growth as a determining factor of social welfare and environmental sustainability is considered very vital. In recent years, remote sensing data has been used as a tool to determine the size of urban expansion and monitor urban growth. The purpose of the present research is to compare the efficiency of pixel-based vector machine kernel functions and object-oriented fuzzy operators in monitoring Tabriz urban growth changes using Sentinel 2 satellite. in order to classify each image based on pixel base support vector machine kernel functions, using support vector machine kernels, the image classification process was performed and the urban growth map of each function was produced for the years under study. ecognition software was used for object-oriented classification. At this stage, segmentation was done based on different scales, shape factor and compression ratio to reach the optimal segmentation mode. Then, teaching points were identified and classification was done using fuzzy operators. Based on the results of this research, the AND fuzzy operator with an overall accuracy of 96.49% and a kappa coefficient of 0.9688 for the image of 2014 and an overall accuracy of 97.31% and a kappa coefficient of 0.9725 for the image of 1403, the accuracy value provided more. Therefore, considering the greater accuracy of object-oriented fuzzy operators , it can be stated that object-oriented processing algorithms of satellite images in the classification of digital satellite images, compared to support vector machine algorithms, make it possible to achieve higher accuracy in extracting the urban area of ​​Tabriz.

رشد شهری به عنوان یک عامل تعیین کننده رفاه اجتماعی و پایداری محیطی، بسیار حیاتی به شمار می­آید. در سا­ل های اخیر داده­های سنجش از دور به دلیل داشتن پوشش فضایی مناسب برای مناطق شهری، به عنوان ابزاری منحصر به فرد برای تعیین اندازه گسترش شهری و نظارت بر رشد شهری مورد استفاده قرار گرفته است. هدف از پژوهش حاضر، مقایسه­ کارآیی توابع کرنل ماشین­بردار پشتیبان پیکسل­پایه و عملگرهای فازی شئ­گرا در پایش تغییرات رشد شهری تبریز با استفاده از تصاویر سری زمانی سال­های 1394 و 1403 ماهواره سنتینل 2 می­باشد. در این راستا، جهت طبقه­بندی هر تصویر بر اساس توابع کرنل ماشین­بردار پشتیبان پیکسل­پایه، در نرم­افزار ENVI با استفاده از کرنل­های خطی، چندجمله­ای، پایه شعاعی و سیگموئید، فرایند طبقه­بندی تصاویر انجام شد و نقشه رشد شهری هر کدام از توابع برای سال­های مورد مطالعه تولید شد. از نرم­افزار ایکاگنیشن جهت قطعه­بندی و طبقه­بندی مبتنی بر عملگر­های فازی شئ­گرا استفاده گردید. در این مرحله اقدام به قطعه­بندی بر اساس مقیاس­ها، ضریب شکل­ها و ضریب فشردگی­های مختلف جهت رسیدن به حالت قطعه­بندی بهینه گردید. سپس، نقاط تعلیماتی مشخص گردیدند و با استفاده از عملگر­های فازی AND، OR، MGE، MAR، MGWE و ALP طبقه­بندی انجام گردید. با استفاده از نقاط نمونه واقعیت زمینی، ارزیابی دقت برای کلیه نقشه­های تولیدی انجام شد. بر اساس نتایج این پژوهش، عملگر فازی AND با دقت کلی 49/96 درصد و ضریب کاپای 9688/0 برای تصویر طبقه­بندی شده سال 1394 و دقت کلی 31/97 درصد و ضریب کاپای 9725/0 برای تصویر طبقه­بندی شده سال 1403، مقدار دقت بیشتری را ارائه نمودند. لذا با توجه به دقت بیشتر عملگرهای فازی شئ­گرا در این پژوهش، می­توان ابراز نمود که الگوریتم­های پردازش شئ­گرای تصاویر ماهواره­ای در طبقه­بندی تصاویر رقومی ماهواره­ای در مقایسه با الگوریتم­های ماشین­بردار پشتیبان، دست­یابی به دقّت بالاتر را در استخراج محدوده شهری کلانشهر تبریز امکان­پذیر می­س
