In this problem, (filter), I'm receiving all green from check50. But when I ran valgrind for blurring I got the following error:

Same thing happens for edging. Now, after spending some time, I understood that something is wrong in helpers.c file's line 59, 60 and 61. Now, I'm guessing that I've done something wrong with getting RGBTRIPLE's value. Whenever I'm addressing to images[i][j].rgbtRed (or rgbtGreen or rgbtBlue) inside the void blur or void edges function, valgrind is giving me error.
I also addressed RGBTRIPLE's value in the void grayscale function. But when I run valgrind ./filter -g in.bmp out.bmp, there's no error. I'm confused here
