What's a "projection histogram of binary image" ? google tells me it's related to "image registration" (alignment of two or more images)

but what are you wanting to smooth ?

i have read one journal paper, they said, first get projection histogram which are obtained by counting the number of black pixels on the binary image, then smoothing is performed to the histogram. so i want to know how to smooth this histogram?thanks

Make little steps my friend: start with a good C++ tutorial.

There are several smoothing/convolution algorithms that you can use to smooth the projection histogram. You can begin your research by using a gaussian smoothing filter.

The lesser known polynomial filter (Savitsky-Golay) may produce a more accurate result depending on your area of research.

How can I make my modal dialog to close and return an id defined by me (IDBACK) when the user clicks on a third button I've added (<<Back)??

Hi all.
See i am reading certain mails i want to sort them by mailDate in Decresing order...and write into xml..

Now i am reading the mail as it is and writing into xml file...

how i can compare it and write so it will be in ascending order..

for(int y=0; y<(linfo->ACL_STMAIL[0].iMBUserMailCount); y++) 							

								{						
									
									_tprintf("\nMails found between %s date and %s date\n",linfo->sStDate,linfo->sEndDate);					 									 
									mailDatee = linfo->ACL_STMAIL[y].cMBUserMailDate;
									mailDatee.Remove('/');										
									if(linfo->ACL_STMAIL[y].bMBUserMailHasAttachment)
									{
										//FileExt = strtok_s(string,"* ,",context);
											
										AttachCount=linfo->ACL_STMAIL[y].iMBUserMailAttachFileCount;	
										for(int i = 0;i < (linfo->ACL_STMAIL[y].iMBUserMailAttachFileCount); i++)
										{
                                          											elementName [0] = "NAME";
											elementValue[0] = linfo->ACL_STMAIL[y].cMBUserMailFromName;
											elementName [1] = "EMAIl";
											elementValue[1] = linfo->ACL_STMAIL[y].cMBUserMailFromEmail;
											elementName [2] = "DATE";
											elementValue[2] = mailDatee;
											elementName [3] = "TITLE";
											elementValue[3] = linfo->ACL_STMAIL[y].cMBUserMailSubject;
											elementName [4] = "BODY";
											elementValue[4] = linfo->ACL_STMAIL[y].cMBUserMailTextDesc;
