Question

在matlab中编译为c代码imcrop无法运行。有没有其他方法可以抑制？

我正在使用Matlab2016a。以下是代码段：

function signal = detectFatigue(im)

% Create a detector object
faceDetector = vision.CascadeObjectDetector('ClassificationModel','FrontalFaceLBP','MinSize',[100 100]);
faceDetectorLeye = vision.CascadeObjectDetector('EyePairBig');

% Detect faces
bbox = step(faceDetector, im);

if ~isempty(bbox);
bbox = bbox(1,1:4);
Ic = imcrop(im,bbox);
bboxeye = step(faceDetectorLeye, Ic);

if ~isempty(bboxeye);
    bboxeye = bboxeye(1,1:4);
    Eeye = imcrop(Ic,bboxeye);
    [~, nce, ~ ] = size(Eeye);
    % Divide into two parts
    Leye = Eeye(:,1:round(nce/2),:);
    Reye = Eeye(:,round(nce/2+1):end,:);

    % make grascale
    Leye = rgb2gray(Leye);
    Reye = rgb2gray(Reye);

    Leye = filterim(Leye);
    Reye = filterim(Reye);

    lroi = [ 12 5 30 16 ];
    rroi = [ 18 5 30 16 ];
    Leyeroi = imcrop(Leye,lroi);
    Reyeroi = imcrop(Reye,rroi);

    [lc, ~ ] = findcircle(Leyeroi);
    [rc, ~ ] = findcircle(Reyeroi);
    if isempty(lc) && isempty(rc)
        signal = 1;
    else
        signal = 0;
    end
end
end

function Leye=filterim(Leye)
    se = strel('disk',2,4);
    % dilate graysacle
    Leye = imdilate(Leye,se);
    % erode grayscale
    Leye = imerode(Leye,se);            
    Leye = imadjust(Leye);
    Leye = imcomplement(Leye);
    Leye = im2bw(Leye,0.95);
    Leye =  imresize(Leye,[30 60]);

function [c, r] = findcircle(Leyeroi)
    [c ,r ] = imfindcircles(Leyeroi,[5 9],'ObjectPolarity','bright','Sensitivity',0.95);
    [rm,id] = max(r);
    r = rm;
    c = c(id,:);
    if ~isempty(c)
        c(1) = c(1) + 15;
        c(2) = c(2) + 7;    
    end

编辑： fullcode

function  testdetectFatigue()

vid=webcam(1);
for loop=1:10
im=snapshot(vid);
detectFatigue(im);
end

并测试下面的detectFatigue.m是函数

@JsonUnwrap

Matlab：在C代码生成时imcrop抛出错误
