Hi, I am using Telosb Tmote with stm25p flash. My task is to store a jpeg image in the flash and find out the edge of the object in image .Image size is 23kb and there are approx 32000 bytes in it . In my algorithm to detect edge I have to take RGB pixel sets one bye one and substract them from the following set of RGB . All this process takes about the calculation of 32000 times subtractions . when I run the program in my PC it takes hardly 1 sec to get me the edge coordinates, how ever using the telosb it takes 45 minutes to detect the edge (what i do is read 3 byte at a time from the flash STM25p process it then increment seek position again process and so on) I want to reduce the time Is there any method in which I can process it faster ? rupesh IIT delhi _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
