Feature-based Automatic Image Stitching Using SIFT, KNN and RANSAC

Random sample consensus (RANSAC) is an iterative method to estimate parameters of a mathematical model from a set of observed data that contains outliers, when outliers are to be accorded no influence on the values of the estimates. Therefore, it also can be interpreted as an outlier detection method. It is a non-deterministic algorithm in the sense that it produces a reasonable result only with a certain probability, with this probability increasing as more iteration… TīmeklisApplying the Feature-based Automatic Image Stitching Using SIFT, KNN and RANSAC into the input images with an overlap distance of 50 cm, the resulting images are as follows (Table2): Table 2: Shows the input image (query and training image) and the resulting stitched image. happy birthday vato loco
