【摘要】:隨著遙感圖像數(shù)量的急劇增加,基于內(nèi)容的遙感圖像檢索系統(tǒng)已成為一個(gè)研究熱點(diǎn)。該文在以綜合區(qū)域匹配算法為圖像相似度度量的前提下,提出了以空間綠顏色特征值降序排序的遙感圖像數(shù)據(jù)庫植被區(qū)域檢索方法。首先,用綜合區(qū)域匹配算法對圖像進(jìn)行相似度度量;然后,依據(jù)這些圖像的空間綠顏色特征值對圖像進(jìn)行降序排序,從而得到含有植被區(qū)域這一高級語義特征的檢索結(jié)果。實(shí)驗(yàn)表明:該方法將檢索查準(zhǔn)率提高了20%,檢索效率明顯提高,可滿足用戶的需求。
[Abstract]:With the rapid increase in the number of remote sensing images, content-based remote sensing image retrieval system has become a research hotspot. This paper presents a method of vegetation region retrieval in remote sensing image database based on descending order of spatial green color eigenvalues. Firstly, the synthetic region matching algorithm is used to measure the similarity of images. According to the spatial green color characteristic value of these images, the image is sorted in descending order, and the retrieval result with the high-level semantic feature of vegetation region is obtained. The experimental results show that the retrieval accuracy rate is increased by 20%, and the retrieval efficiency is obviously improved by this method. Can meet the needs of users.
