MATLAB第二轴用于遵循惯例的颜色条

Question

我想为假彩色图像的相同颜色条制作第二个轴。第二个比例应遵循以下惯例：[新值] = Log10（[旧值] / 108000）/ - 0.4。我有第一轴的代码：

C = 10
hFig = figure('Name','False Color Luminance Map', 'ToolBar','none','MenuBar','none');
% Create/initialize default colormap of jet.
cmap = parula(16); % or 256, 64, 32 or whatever.
% Now make lowest values show up as black.
cmap(1,:) = 0;
% Now make highest values show up as white.
cmap(end,:) = 1;


imshow(J,'Colormap',cmap) % show Image in false color

colorbar % add colorbar


h = colorbar; % define colorbar as variable
caxis auto
y_Scl = (1/C);
yticks = get(h,'YTick');
set(h,'YTickLabel',sprintfc('%g', [yticks.*y_Scl]))

在上一篇文章中我得到了第二轴的这条线：

BarPos = get(hBar1,'position');
ylabel(hBar1,'label','FontSize',12);
haxes = axes('position',BarPos,'color','none','ytick',0:5:15,'ylim',[0 15],'xtick',[]);

如何让第二轴使用第一轴的yticks作为约定的输入？

编辑：这是我想出的。事情是价值观错误：/

fname='IMG_0041'; % select target image
C = 1000; % Constant to adjust image
K = 480; % Cameraconstant



RGB = imread([fname, '.tif']);% Read Image as tif
info = imfinfo([fname,'.CR2']); % get Metadata from CR2
x = info.DigitalCamera; % get EXIF
t = getfield(x, 'ExposureTime');% save ExposureTime
f = getfield(x, 'FNumber'); % save FNumber
S = getfield(x, 'ISOSpeedRatings');% save ISOSpeedRatings
date = getfield(x,'DateTimeOriginal'); % save DateTimeOriginal
I = rgb2gray(RGB); % convert Image to greyscale
% N_s = K*(t*S)/power(f,2))*L 
L = power(f,2)/(K*t*S)*C; % calculate L/N_s
J = immultiply(I,L);

hFig = figure('Name','False Color Luminance Map', 'ToolBar','none', 'MenuBar','none');
% Create/initialize default colormap of jet.
cmap = parula(16); % or 256, 64, 32 or whatever.
% Now make lowest values show up as black.
cmap(1,:) = 0;
% Now make highest values show up as white.
cmap(end,:) = 1;


imshow(J,'Colormap',cmap) % show Image in false color

colorbar % add colorbar


h = colorbar; % define colorbar as variable
caxis auto
y_Scl = (1/C);
yticks = get(h,'YTick');
set(h,'YTickLabel',sprintfc('%g', [yticks.*y_Scl]))


BarPos = get(h,'position');
haxes = axes('position',BarPos,'color','none','ylim',[0 150]);
set(haxes,'YTickLabel', sprintfc('%g', log10(yticks.*y_Scl/108000)/-0.4));
