When the user selects an image file, you need to do feature extraction on that image file in the same way as it was done on the sample images, and then you need to match the features to those stored to find the closest match.
The questions then become (1) how much weight to give to the distance between the test features and the ideal features; and (2) how far away from the ideal features should be allowed before the program says "I don't know".
Unless, that is, the intention is to be able to input images of fruits or vegetables that the program was not given specific information about, and the program is required to estimate whether "fruit" or "vegetable" is more likely ?

If you want, you can save whatever you want
v=[1.23 5.26;4.56 7.25]
text={'fruit','vegetable'}
save filename Im1 Im2 v text

Suppose you want image1
text{1} % for image1
text{2} % for image2
Elys maybe you should read some basis matlab programming
