逆投影器 的英文怎麼說
中文拼音 [nìtóuyǐngqì]
逆投影器
英文
backprojector-
This thesis developed an algorithm to reconstruct the wavelet coefficients of an image from the radon transform data. this algorithm is similar to the conventional filtered backprojection algorithm, except that the filters are now angle dependent, and the backprojection gives us the wavelet coefficients of the reconstruction, which are then used to synthesize the reconstruction
該演算法與傳統的濾波反投影法相似,不同的地方在於,演算法中用到的濾波器是與x射線的照射角度相關聯的,而且反投影后得到的是待建圖像的小波分解系數,這些系數再經過逆小波變換就得到了最終的重建圖像。
