no, this is good enough for my use,
as i just need a measure of time taken for the whole code as one, and time taken for each of the operation in the code done seperately.

but if there is a...

i was just wondering, is there a convertion ratio between the clock ticks and the actual time in milliseconds?
i also understand the clock ticks vary according to the processor, right??

the code is working fine, except that the time it calculates is a bit lesser than what my stopclock shows.

is it the case here??

i am using C.

i will check them out, thanks..

Hi,

i would like to calculate the execution time of my program.
is there any function available to enable it??

u can use this code;

#include<stdio.h>
int main(void)
{
FILE *fp;
unsigned char image[256][256];
int r,c;

if((fp = fopen("f16.dat","r+")) == NULL)

one easy way to do it is,

declare image and header array;

unsigned char Header[0x435],image[256][256];


and to read image;

thanks , i got the idea.

i really liked that do_what_i_want_it_to_do(); function and the baby-safe example..
but the problem is, the whole porgram is some 500 codes, so i submitted only the pertinent code.

i just want to...

if i am any better in C, why should i ask for help. :-)
with what little time i have, i have to finish the job at hand, and with what little C expertise i have. so...

thanks for the help,
google yields hits, ok. but the problem is that all the codes are in high level C, unfortunately i am not that good in C. so i want the coding in simple C.

ok i can outline...

Hi,

i am using pow command quite frequently in my codes, and i have a feeling that i may be using it incorrectly.
foe ex:

image[x][y] is unsigned char and 2 is numeric, so...

Hi,

i am trying to implement gabor filter for image enhancement.
if someone has any code snippet or pseudocode or any idea of implementing it in C, please help me out with it.

thanks.

i am using Turbo C 3.0, when you say another compiler, what do you mean,
can you name some good free downloadable ones..

hi,
is there no procedure wherein you can allocate memory by malloc etc..
my whole code is in TorboC and i cant change it to another compiler.(atleast now)..

thanks........

hi,

in turbo C the maximum array size i am able to specify is array[250][250]..
what should i do to enlarge this size to say..array[512][512]..
i dont know a thing about memory allocation,
so...

i tried this code for rotating,
but for r1 and c1, i am getting negative values..
and the rotation is also not proper..

hi,
i have to rotate an image. the image is stored in an image[rows][cols] array..
i am trying to rotate it using trignometric functions.
i am not sure what happens when i rotate the image,
does...

i guess that the .dat file does not have a file header, and the info is stored as data bits, and can be represented in an 2d array.
now moving a little further, how to rotate this image in an array....

next time i cut a chunk of code from a bigger program i will remember narue, and modify it b4 submitting it.
anyways i thought it is enough to get the message through than the aesthetic appeal of...

hi narue,
nice try..but i still think that you suck.. never mind..
the reason i posted that code with all the flaws and pitfalls as you have described it, is because i was also finding the same...

well well well guys, what all this???
hi narue..
i am a newbie and if i am not ignorant i might as well be a great genius like you and not an 'ignorant newbie'..
and what was the other thing u...

for starters u can get the image (100x100 pixels) in this way..
then alter the value of each pixel to change the image..

hi,
i am writing an image into an array.
well i want to know the difference of having this command 'fprintf(fp1,"\n");'
in the following code..

fp1=fopen("f16.raw","w");

well i guess turbo C can accept a max array size of [250][250]..
above that it gives an error..

but for starters i took unsighned char image[250][250]
now i have to change this gray scale image...

i have an 256x256 grayscale image in .dat format.
i am reading the file in turbo C in an 2d char array and comparing with another similar picture to check if they are the same..
and i am doing some...

yes vegaseat, char stores 1byte.
but with 128 characters, how will it represent 256 levels????

or am i overlooking a simple fact..i dono...

sounds kinda simple, but i am a C novice, so looks very complicated for my understanding.

if some example codes are there, it will help me understand it.
please..anybody......

if i am asking...

thanks a lot vegaseat..
ur code is working great..

i am actually reading a gray scale image, which has 0-255 levels of gray intensities.
so each pixel in the image or each character represents a...

hi,
i have to do image read and write in Turbo C.
i am very new to C.
so please help me out as to how to do these operations and provide some sample code if you have any..
i have a vague idea...
