When I convert an image from BMP to JPEG using the code below:
BMP = imread('CYMR9_SCAP_VE_MEAS_FIB_MEASURE5_p003_2013-09-18_20-07-21.bmp','bmp');
imwrite(BMP,'CYMR9_SCAP_VE_MEAS_FIB_MEASURE5_p003_2013-09-18_20-07-21.jpg','jpg');
imageOriginal = imread('CYMR9_SCAP_VE_MEAS_FIB_MEASURE5_p003_2013-09-18_20-07-21.jpg');
it saves the image in my directory as 147KB. However when I open the original image in it's BMP format in Paint and save it manually as a JPEG it saves as the size 386KB!
I'm working with a function based around automated image processing and would prefer Matlab to convert the initial image to the size 386Kb (similar to manual conversion using paint) as when it's at the size 147KB my function doesn't work.
could anyone help solve this problem??

You don't need the second argument. It will figure out the format from the filename extension.

Play with the 'Mode' and 'Quality' options of imwrite(). Look in the imwrite() documentation under "Name-Value Pair Arguments"
