MATLAB: Using imsharpen with imagesc

image analysisimage processing

Can you use imsharpen with imagesc?
Trying to use imshapren with the following code:
figure
PLIFData_rot = (flipud(PLIFdata(:,:,imFrame)));
FiltImPLIF = imguidedfilter(imgaussfilt((PLIFData_rot)));
imagesc(xVecPLIF,yVecPLIF,double(FiltImPLIF)/double(max(max(FiltImPLIF))));
set(gca,'YDir','normal');
colormap('hot');
caxis([0 .1]);
xlabel('x');
ylabel('y');
pbaspect([50 50 1]);

Hi, from your previous comment it seems that you are trying to pass the image object returned by imagesc() into the input of imsharpen(). Something like below,
I = imagesc(xVecPLIF,yVecPLIF,double(FiltImPLIF)/double(max(max(FiltImPLIF))));
sharpenImage = imsharpen(I);
In the code above I is an matlab.graphics.primitive.Image object whereas, input of imsharpen() is designed to be a grayscale or truecolor (RGB) image one of these types: uint8, int8, uint16, int16, uint32, int32, single, double.
Instead, try this
FiltImPLIF_Sharpen = imsharpen(double(FiltImPLIF)/double(max(max(FiltImPLIF))));
