performance evaluator for edge detection or binary images
i need some help to evaluate result from edge detection and/or binary
image, anyone know about the method and the MATLAB code?
Really appreciate the help. Thank you in advance.
...performing canny edge detection on V component on HSV image
Hi, I tried removing the effect of light on an image. I converted the
colored image from an RGB to HSV and filtered the V or(I) component.
Now I am trying to perform a Canny edge detection on the resultant
image but I am getting problems. Help!

Sounds like you are making progress in the forward di...Rotation Invariant Face Detection : how to deal with out of boundaries pixels in rotated images
I'm working on a neural network based face detection project.
We have a router network wich finds out the rotation angle.
Trying to rotate an existing training set of frontal not rotated faces (i.e.
CMU training set) i have found some troubles when i try to interpolate
(estrapolate?) pixel out of boundaries in rotated images.
I need some interpolation (estrapolation?) tecnique to fill the empty spaces
in a 20x20 pixel window applyed over the rotated image. Such tecnique has to
preserve pixel correlation without creating "non sense" pixels which could
disturb the router neural ne...Creating image database to implement Viola Jones face detection method
Is it the necessity to create my image database in .pgm format to implement Viola Jones face detection method. Can I create my image database for training in .jpg format.
Thanks in advance

This depends on what tools or libraries you are using. Are you

whenever i use subplot to plot an array of images, if i want all the images to be square, and i have >2 columns, the spacing between the rows is way too big. for example:
if anybody knows of a quick work around for this, i'd love to know about it.
...classification of images as face image & nonface image
I am new here working on image processing .
I have set of cropped images having faces in it but there are some images in it which does not have faces.
I am using PCA for making classification
I have done following steps.
1.created data set of training images.
2. calculate average of these data set & subtracted from data set matrix.
3.applied PCA to find eigen vectors of covariance matrix.
After that I don’t know what to do.
Can you give me guideline to go forword.
Waiting for your reply.
thanks in advance.

Is your question how to project an image onto a 3D surface?
Look up 'surface' in matlab help- they explain it better than i can

i would like to convert a 240x320x3 matrix, which is made out of a
240x320x3 12bit rgb image, into a 240x320x1 8 bit indexed image.
i asked that question already yesterday, but didn't have much luck
with the suggestions.
so if anyone could help me, it would be great.
what i tried until now is:
C12RGB = cat(3, ZCRED, ZCGREEN, ZCBLUE);
I = mat2gray(C12RGB);
[X,map] = gray2ind(I,256);
-> this gives me a 240x320x3 image not a 240x320x1 image
C12RGB = cat(3, ZCRED, ZCGREEN, ZCBLUE);
[ C8FARBE, map ] = cmunique( C12RGB );
-> this generates a map which is to large, as i'm just a...
