[討論] 四元樹S = qtdecomp(I,fun)用法

根據 Matlab的定義
S = qtdecomp(I, fun) uses the function fun to determine whether to split a
block. qtdecomp calls fun with all the current blocks of size m-by-m stacked
into an m-by-m-by-k array, where k is the number of m-by-m blocks. fun
returns a logical k-element vector, whose values are 1 if the corresponding
block should be split, and 0 otherwise. (For example, if k(3) is 0, the third
m-by-m block should not be split.) fun must be a function handle.

想請教大家,關於這個fun
我應該要怎麼去設定,才對得到我想要的結果
我fun的設定打算用:
假如周邊的值<2,那就Merge.
(2)
假如我的I不局限於灰階影像
想用彩色影像當Input,要怎麼修正呢
抱歉打擾了

印象中限定input為grayscale image.建議靠rgb2ycbcr取出luminance的部分,處理完之後,再加回cbcr,拿ycbcr2rgb轉回rgb影像.
