我使用颜色阈值应用程序创建了一个蒙版函数。我想通过该函数运行多个图像,而不是单独运行每个图像。例如,“Control_1 Negative P001(30).png”、“Control_1 Positive P001(30).png”等,直到 Control_41 Positive 和 Negative .png 文件。我假设您会使用 for 循环,但我不确定从那里去哪里。
function [BW,maskedRGBImage] = GlassBrainMask(RGB)
%createMask Threshold RGB image using auto-generated code from colorThresholder app.
% [BW,MASKEDRGBIMAGE] = createMask(RGB) thresholds image RGB using
% auto-generated code from the colorThresholder app. The colorspace and
% range for each channel of the colorspace were set within the app. The
% segmentation mask is returned in BW, and a composite of the mask and
% original RGB images is returned in maskedRGBImage.
