    <p>Hi I am trying to do image processing with python. what i actually want to do is i have image with human and i need to indetify human faces or detect circle (basically human face). what i have done so far us </p> <ol> <li>i have done edge detection for image using sobel edge detection.</li> <li>than i have converted image into binary image which saves binary image ad prints out array of the image which is 0 or 255 (Black and White) </li> <li>now what i m confused about after this what can i do to detect circle in image and print out how many human present in image. </li> <li>i am using still images so i am giving the input for the image </li> </ol> <p>i am using Python, PIL, numpy and scipy. i do not want to use opencv. i want to detect human face and count how many people are in image and than print out the number of people in image. </p> <p>i would be so greatful if someone can help me out and tell me what can i do for this problem? </p> <p>Thanks in advanced. </p> <pre><code>import numpy import scipy from scipy import ndimage im = scipy.misc.imread('test5.jpg') im = im.astype('int32') dx = ndimage.sobel(im, 0) # horizontal derivative dy = ndimage.sobel(im, 1) # vertical derivative mag = numpy.hypot(dx, dy) # magnitude mag *= 255.0 / numpy.max(mag) # normalize (Q&amp;D) scipy.misc.imsave('sobel.jpg', mag) </code></pre> <p>The code above its not mine i got it from online. </p> <p>i have also asked this question in other forum as well.<a href="http://forums.devshed.com/showthread.php?p=2857698&amp;mode=linear#post2857698" rel="nofollow">HERE</a></p>

    1. COyou're going to regret that idea, NOT using opencv ;)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
