最近很想拼一下進度,因為想去參加花蓮的會議(嘿啦!我一向動機不純…),本打算在上星期把草稿擠出來,但as usual,每到想要拼的時候,就會有一些有的沒的大小事情來擾亂,弄得我其實這十天來的進度幾乎是零…然後也沒心情想要拼了…

雖然理論上來說是不會,但實際操作上,某些 shape descriptor 其實是會被 object 在 digital image 上的大小影響,也就是和 spatial resolution 有關,要解決這個問題,有必要把每個 object 都 resize 到同一個大小…

想要把兩個或兩個以上的structure合併,結果當然是遇到了問題,且事情不如想像的容易,尤其是當要合併的個數不定,各structures也並非一定是named structure,且不同structure中的tag_name也許會重覆…
