So my take is that if you just want to convert to grayscale using some default implementation, use IrfanView, but if you need more flexibility, options, and perhaps want to compose different batch processing actions together, use more professional tool like the one I mentioned. T Bitmap Int width, height Colour background Colour map F (width 40, height 40, background white) assert(width > 0 & height > 0). And if you need, it has a host of other image processing functions like brightness, contrast, etc. Step 1 Upload bmp-file (s) Select files from Computer, Google Drive, Dropbox, URL or by dragging it on the page. 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. imageiio.imread(uri'data/eight.tif')plt. Using imageiogives us more flexibility, especially when it comes to handling metadata. It is commercial, but allows one to specify how much Red, Green, and Blue contribute, as well as allows one to use Lightness or Intensity "channels" of other color models like HSL and HSI to achieve conversion: Batch Image Processor In addition it has various options for saving grayscale images: 8-Bit Bitmap, 8-Bit PNG, 8-Bit GIF, and some others. while skimageis dedicated to performing operations on the images.

To determine which color space is used, use imfinfo to get information about the graphics file and look at the value of the PhotometricInterpretation field. However, for those who might want to specify exactly how the colors are to be converted to grayscale I thought I will mention the program I use. Convert your image to another type to use bmp (or use png) imwrite (im2single (newimage), 'newimage.bmp') or imwrite (im2double (newimage), 'newimage.bmp') or imwrite (im2uint8 (newimage), 'newimage.bmp') Depending on your data and desired precission. If the color image uses the CMYK color space, A is an m-by-n-by-4 array. If you just want to convert to grayscale using default conversion method, IrfanView does the job. Even though there is an accepted answer, thought I would give my 2 cents.
