fourier image technique 中文意思是什麼
fourier image technique
解釋
傅里葉成像技術-
In recent years, the worldwide researchers pay much attention to fourier telescopy. it is an active imaging technique that encodes the information in the temporal instead of spatial domain, then receives the speckle and deposed of it to reconstruction the object image. now, the high - resolution technique is under the condition of deeply researched
它是一種主動式干涉成像技術,這一技術通過時域內的相位的調制完成直線條紋對目標的掃描,從而達到對深空目標頻譜的抽樣,然後接收其散射回波,對回波信號進行處理,進而還原出目標的像。 -
The technique constructs bpof based watermark from the image discrete fourier transformation and embeds the watermark into the bit plane ( s ) of the corresponding magnitude spectrum
它在圖像離散fourier變換域構造基於二元純位相濾波器的水印,並嵌入到其相應的幅值位平面中。
