the small part of the finger above the leaf is really difficult for me to remove. I tried to remove it based on Hue, but it also remove the brown parts of the leaves.
How can I remove everything except leaves?

Use a combination of hsv and activecontour
I=imread('Finger2.png');
hsv=rgb2hsv(I);
m=(hsv(:,:,1)>0.08 & hsv(:,:,1)<0.2);
m2=activecontour(hsv(:,:,1),m,'edge','ContractionBias',-0.1);
imshow(m2)

mmmm.
How about this?
I=imread('Finger2.png');
hsv=rgb2hsv(I);
m=(hsv(:,:,1)>0.08 & hsv(:,:,1)<0.2);
m=imfill(m,'holes');
m=bwmorph(m,'majority',25);
m2=activecontour(hsv(:,:,1),m,'edge','SmoothFactor',1.5);
imshow(m2)
It doesn't work as good as last one though.
Try some dilation and erosion too.

hi
By
imtool
command find exact threshold for leaves color and apply segmentation for that color only finger will be automatically remove d
while fixing threshold use separate threshold for R, G, B with | & conditions
