我正在从文件夹"c1"访问10个图像,我有查询图像.我已经实现了在单元格数组中加载图像的代码,然后我将逐个计算查询图像与文件夹"c1"中每个图像之间的直方图交集.现在我想绘制精确回忆曲线,但我不知道如何编写代码以使用从直方图交叉点获得的数据获得"精确回忆曲线".我的代码:
Inp1=rgb2gray(imread('D:\visionImages\c1\1.ppm'));
figure, imshow(Inp1), title('Input image 1');
srcFiles = dir('D:\visionImages\c1\*.ppm'); % the folder in which images exists
for i = 1 : length(srcFiles)
filename = strcat('D:\visionImages\c1\',srcFiles(i).name);
I = imread(filename);
I=rgb2gray(I);
Seq{i}=I;
end
for i = 1 : length(srcFiles) % loop for calculating histogram intersections
A=Seq{i};
B=Inp1;
a = size(A,2); b = size(B,2);
K = zeros(a, b);
for j = 1:a
Va = repmat(A(:,j),1,b);
K(j,:) = 0.5*sum(Va + B - abs(Va - B));
end
end
两个对象是否可以具有相同的余弦和Tanimoto系数距离测度，其中
Tanimoto distance measure, d(x,y) = x.y / (|x|*|x|) + (|y|*|y|)- x*y
和
cosine measure, d(x,y) = x.y /(|x|* |x|) * (|y| *|y|)
我在流星应用程序中实现了一个jquery滑块表单.当我点击表单的提交按钮时,它应该调用clent.js文件中的javascript函数addme().但它没有用.此外,表单不是模板.我知道使用template.templatename.events我们可以执行事件.但是,我很好奇,正常的"onclick"事件在流星中起作用了吗？
我在这个网站上使用了jquery菜单:http: //alijafarian.com/jquery-horizontal-slideout-menu/

我的代码:
Inp1=rgb2gray(imread('D:\visionImages\c1\1.ppm'));
figure, imshow(Inp1), title('Input image 1');
num_bins = 32;
A = imhist(Inp1, num_bins);

B = zeros(num_bins, 30);
ptr=1;
for i = 1 : length(srcFiles)
filename = strcat('D:\visionImages\c1\',srcFiles(i).name);
I = imread(filename);
I=rgb2gray(I);
B(:,ptr) = imhist(I, num_bins);
ptr=ptr+1;
end
% histogram intersection
a = size(A,2); b = size(B,2);
K = zeros(a, b);
for i = 1:a
Va = repmat(A(:,i),1,b);
K(i,:) = 0.5*sum(Va + B - abs(Va - B));
end
