MATLAB: Image with segments looks different after imread()

image corrupt when imread()image not read in correctlyimport image problem

Hello

I have a question concerning an image with my image segments. I am creating this image using an software for segmentation that exports the resulted images as png file format. The segments look quite good but when I am trying to read in the image in MATLAB using imread() and the use imshow() to display it many gaps in the edge are generated.

Do you know what can cause this problem ? Is it a way to overcome it ?

In the link below you can see an example of my images:

1. Image generated by the software

2. Image displayed using imshow() in MATLAB

Try zooming in in the figure window, the points are probably still there, just not visible when zoomed out due to resizing/resolution within the figure window.

Are you sure it's not reading them correctly but you're just viewing a small range?

try:

imshow(imread('example.bmp'),[]); %whole range

Edition:

What class is the bitmap file?

I = imread('example.bmp');
class(I)

and then what class is the corresponding JPG file?

I = imread('sameexample.jpg');
class(I)

MATLAB: Quality for Image in matlab gui

If you display a large image in a smaller area, or if you display a small image in a larger area, then the quality will not be high.

If you have a small image and you are using image() or imagesc() to display it, then use

axis image

to tell MATLAB to use one pixel per array element. That could end up showing a small image, but the quality will be preserved.
