Embodiment 1
[0065] Such as figure 1 As shown, the embodiment of the present invention provides a method for extending the depth of field of a microscopic image, including:
[0066] Step 11: Set a reference image from multiple microscopic images with different focus.
[0067] In this step, the microscopic image is a color image, and multiple focused microscopic images of the same object will be generated due to focal length transformation and movement of the objective lens when the microscope is framing a view. In these different focused microscopic images, The depth of field of each microscopic image is also different, and these differently focused microscopic images belong to the source image. In this step, a microscopic image is selected from a plurality of different focused microscopic images as a reference reference image, so that in subsequent steps, this reference image can be used as an extended reference to realize matching, fusion and other expansion schemes. Then, when selecti...
Embodiment 2
[0096] Such as Figure 5 As shown, the embodiment of the present invention provides a depth of field expansion device for microscopic images, including:
[0097] An image reference module 101, configured to set a reference image from a plurality of different focused microscopic images;
[0098] Image transformation module 102, for reading reference image and remaining new image and carrying out color space transformation;
[0099] An image matching module 103, configured to perform pixel-level matching on the remaining new image and the reference image in the transformed color space;
[0100] The image fusion module 104 is used to fuse the matched image and the reference image using wavelet transform algorithm;
[0101] The image reconstruction module 105 is configured to reconstruct the fused image by wavelet inverse transform and output the reconstructed image.
[0102] The device of the embodiment of the present invention also includes an image judging module 106, which is...
