how to change the color of one portion of an image to another portion of the same image using MATLAB -


i have color image. image consists of object has shadow. have removed shadow shadow portion's color not similar background color .now how can match color using matlab coding?

you can change matlab matrix (here called img) corresponds image. example, changed pixels of shadows -20. can indexes doing

indexes = (img == -20)

to change values background color, assumed equals 100 example, set doing

img(indexes) = 100

since you're working color images, need 3 color matrices corresponds image. in case have background color each layer, repeat process

indexes1 = (img(:, :, 1) == shadow_color_layer_1)

indexes2 = (img(:, :, 2) == shadow_color_layer_2)

indexes3 = (img(:, :, 3) == shadow_color_layer_3)

img(indexes,1) = background_color_layer_1

img(indexes,2) = background_color_layer_2

img(indexes,3) = background_color_layer_3

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
