MSER features detection not working in matlab

Why is that whenever I try to use detectSURFFeatures(img) with a binary image in matlab gives me proper points but whenever I use detectMSERFeatures(img) with the same binary image
gives me error instead of pointing some valid regions?

ERROR: 

Error using detectMSERFeatures
Expected input number 1, I, to be one of these types:

uint8, int16, uint16, single, double
Instead its type was logical.

Error in detectMSERFeatures>parseInputs (line 75)
validateattributes(I,{'uint8', 'int16', 'uint16', ...

Error in detectMSERFeatures (line 64)
[Iu8, params] = parseInputs(I,varargin{:});
Solution

  • Try this: make image 2 double first by using img=im2double(img); then feed it to MSER detectMSERFeatures(img)
