Abstract
An image interpolation method comprises applying a filter to an RGBIR image to generate a LUMA image; calculating two gradients according to the LUMA image; and interpolating a missing pixel between two pixels in the RGBIR image according to the two gradients. Wherein each gradient corresponding to two LUMA pixels in the LUMA image. An image fusion method comprises applying a filter to an RGBIR image to generate a LUMA image; obtaining an R-image, a G-image, a B-image and an IR image according to the RGBIR image; and generating a fusion image according to the R-image, G-image, B-image, the IR image and the LUMA image.
Claims20
An image interpolation method comprising:
- applying a filter to an RGBIR image to generate a LUMA image directly from the RGBIR image;
- calculating two gradients according to the LUMA image, each gradient corresponding to two LUMA pixels in the LUMA image;
- and
- interpolating a missing pixel between two pixels in the RGBIR image according to the two gradients.
An image fusion method comprising:
- applying a filter to an RGBIR image to generate a LUMA image;
- obtaining an R-image, a G-image, a B-image and an IR image according to the RGBIR image;
- generating a fusion image according to the R-image, G-image, B-image, the IR image and the LUMA image.
