我尝试通过在SQL中原型化该函数(Dummy)来确定将传递哪些参数:RETURNS TABLE') "data", FROM images -- which actually is another WITH subrequest ...
SELECT clusterize分解成两个函数是不是更简单,一个"addimage“函数调用每个图像,然后"
function will get SIFT descriptors from training images and def read_and_clusterizesift_keypoints=np.concatenate(sift_keypoints, axis=0) #step 1: read and detect SURF keypoints ov
