SURF는 특징 추출 및 설명 방법을 개선하고보다 효율적인 방법

SURF improves feature extraction and description methods and completes feature extraction and description in a more efficient way. The advantages of the SIFT algorithm are that it is stable in function, maintains invariance to rotation, brightness and scale transformations, and is somewhat stable against perspective transformation and noise. The disadvantage is that the actual applied value is not high and the feature points are smooth when the edges of the image are smooth.

SURF improves feature extraction and descriptive methods and completes feature extraction and description in a more efficient way. The advantage of the SIFT algorithm is that the functionality is stable, the immutability, brightness, and scale conversion to rotation are maintained, and some degree of stability for perspective conversion and noise. The downside is that the actual application value is not high and the feature point is smoother when the edges of the image are smoother, making extraction more difficult.

SURF改进了特点提取和说明方法，以更有效的方法提取和说明完成。SIFT算法的优点是功能稳定，维持对旋转的不变性、亮度和规模变换，对远近转换和噪音有一定的稳定性。缺点是实际适用值不高，当图像边缘光滑时，特点点光滑，提取难度更大<br>
