1. A method for processing an image, comprising:
receiving an image including an array of pixels from a sensor, each pixel in the array of pixels having a value selected from one of three primary colors based on a corresponding position value in a mask pattern;
generating a preprocessed image by performing preprocessing on the image, wherein the preprocessing excludes a reduction of salt and pepper noise, or another reduction of Gaussian noise; and
performing perception on the preprocessed image.
 
13. An apparatus comprising:
at least one processor and memory including executable instructions that when executed perform operations comprising:
receiving an image including an array of pixels from a sensor, each pixel in the array of pixels having a value selected from one of three primary colors based on a corresponding position value in a mask pattern;
generating a preprocessed image by performing preprocessing on the image, wherein the preprocessing excludes a reduction of salt and pepper noise, or another reduction of Gaussian noise; and
performing perception of the preprocessed image.
 
18. A non-transitory computer readable medium having code stored thereon, the code, when executed by a processor, causing the processor to implement a method comprising:
receiving an image including an array of pixels from a sensor, each pixel in the array of pixels having a value selected from one of three primary colors based on a corresponding position value in a mask pattern; and
performing perception on a preprocessed image that excludes a reduction of salt and pepper noise, or another reduction of Gaussian noise.
