Read a series of images with different exposures that were captured from a fixed camera with no moving objects in the scene.

I1 = imread('car_1.jpg'); I2 = imread('car_2.jpg'); I3 = imread('car_3.jpg'); I4 = imread('car_4.jpg');

Display the images. In the underexposed images, only bright regions like headlights have informative details. Conversely, the headlights are saturated in the overexposed images, and the best contrast comes from darker regions such as the brick floor and the roof.

montage({I1,I2,I3,I4})

Blend the images using exposure fusion. By default, theblendexposurefunction attempts to suppress highlights from strong light sources. For comparison, also blend the images without suppressing the highlights. Display the two results.

E = blendexposure(I1,I2,I3,I4); F = blendexposure(I1,I2,I3,I4,'ReduceStrongLight',false); montage({E,F}) title('Exposure Fusion With (Left) and Without (Right) Strong Light Suppression')

In the fused images, bright regions and dark regions retain informative details. With strong light suppression, the shape of the headlights is identifiable, and saturated pixels do not extend past the boundary of the headlights. Without strong light perception, the shape of the headlights is not identifiable, and there are saturated pixels in the reflection of the headlights on the ground and on some parts of the other cars.

Read a series of images with different exposures. The images were captured from a fixed camera, and there are no moving objects in the scene.

I1 = imread('office_1.jpg'); I2 = imread('office_2.jpg'); I3 = imread('office_3.jpg'); I4 = imread('office_4.jpg'); I5 = imread('office_5.jpg'); I6 = imread('office_6.jpg'); montage({I1,I2,I3,I4,I5,I6}) title('Images with Different Exposures')

Blend the registered images using exposure fusion, optionally varying the weight of contrast, saturation and well-exposedness in the fusion, and without reducing strong light sources. Display the result.

E = blendexposure (I1、I2 I3、预告、I5, 16,'contrast',0.8,...'saturation',0.8,'wellexposedness',0.8,'reduceStrongLight',false); imshow(E) title('Blended Image Using Exposure Fusion')
