Problems of using the considered methods within the framework of DLP systems are considered. A new object image processing method was presented that allows processing of complex images. A metric of accuracy and completeness of plagiarism image detection was used to evaluate the quality of the developed method. Testing was carried out using image ranking to analyze the ability of the model to search for semantics. Comparative testing was carried out with the method based on raster neural models. The advantages and disadvantages of the developed method were highlighted, as well as options for fu rther developmentAs a result of this work, a method for processing object images in native format has been developed. The main advantage of the developed method is the high rate of accuracy (87 %) and completeness (100 %). This study can be useful for further research in the field of vector image analysis. Also, the developed method can be applied as a tool similarly to raster methods of image processing (image search, classification, search for objects in the image).</p></abstract><trans-abstract xml:lang="ru"><p>Представлен обзор существующих методов обработки объектных изображений. Рассмотрена проблематика использования рассмотренных методов в рамках DLP-систем. Представлен новый метод обработки объектных изображений, позволяющий обрабатывать сложные изображения. Для оценки качества разработанного метода использовалась метрика точности и полноты обнаружения изображений плагиата, проведено тестирование с помощью ранжирования некоторых изображений для анализа возможности модели искать семантику. Выполнено тестирование для сравнения с методом, основанном на растровых нейронных моделях, выделены преимущества и недостатки разработанного метода, а также предложены варианты дальнейшего развития. В результате разработан метод обработки объектных изображений в нативном формате. Основным преимуществом разработанного метода являются высокие показатели точности (87 %) и полноты (100 %). Данное исследование может быть полезно для дальнейших разработок в области анализа векторных изображений, представленный метод можно применять как инструмент аналогично растровым методам обработки изображений (поиск по изображениям, классификация, поиск объектов на изображении).</p></trans-abstract><kwd-group xml:lang="en"><kwd>convolutional neural networks</kwd><kwd>DLP systems</kwd><kwd>computer vision</kwd><kwd>vector image analysis</kwd><kwd>drawing analysis</kwd><kwd>drawing similarity search</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сверточные нейронные сети</kwd><kwd>DLP-системы</kwd><kwd>компьютерное зрение</kwd><kwd>анализ векторных изображений</kwd><kwd>анализ чертежей</kwd><kwd>поиск схожих чертежей</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Leila Z., Omar E., Dieter R.
