資源簡介
壓縮包中包含的具體內容：
對給定數據中的6個不同場景圖像，進行全景圖拼接操作，具體要求如下：
（1）?尋找關鍵點，獲取關鍵點的位置和尺度信息（DoG檢測子已由KeypointDetect文件夾中的detect_features_DoG.m文件實現；請參照該算子，自行編寫程序實現Harris-Laplacian檢測子）。
（2）?在每一幅圖像中，對每個關鍵點提取待拼接圖像的SIFT描述子（編輯SIFTDescriptor.m文件實現該操作，運行EvaluateSIFTDescriptor.m文件檢查實現結果）。
（3）?比較來自兩幅不同圖像的SIFT描述子，尋找匹配關鍵點（編輯SIFTSimpleMatcher.m文件計算兩幅圖像SIFT描述子間的Euclidean距離，實現該操作，運行EvaluateSIFTMatcher.m文件檢查實現結果）。
（4）?基于圖像中的匹配關鍵點，對兩幅圖像進行配準。請分別采用最小二乘方法（編輯ComputeAffineMatrix.m文件實現該操作，運行EvaluateAffineMatrix.m文件檢查實現結果）和RANSAC方法估計兩幅圖像間的變換矩陣（編輯RANSACFit.m 文件中的ComputeError()函數實現該操作，運行TransformationTester.m文件檢查實現結果）。
（5）?基于變換矩陣，對其中一幅圖像進行變換處理，將其與另一幅圖像進行拼接。
（6）?對同一場景的多幅圖像進行上述操作，實現場景的全景圖拼接（編輯MultipleStitch.m文件中的makeTransformToReferenceFrame函數實現該操作）。可以運行StitchTester.m查看拼接結果。
（7）?請比較DoG檢測子和Harris-Laplacian檢測子的實驗結果。圖像拼接的效果對實驗數據中的幾個場景效果不同，請分析原因。
已經實現這些功能，并且編譯運行均不報錯！
