Systems and methods to distinguish between features depicted in images

A method of distinguishing between features depicted in an image, the method being implemented in a computer system comprising one or more physical processors and non-transitory electronic storage storing machine-readable instructions, the method comprising:

• obtaining information defining an image, the image comprising an array of pixels, the information defining colors for the array of pixels;
• obtaining an identification of a row of pixels as depicting a horizon in the image;
• obtaining distances of multiple ones of the pixels from the row of pixels, the multiple ones of the pixels including a first pixel located a first distance above the row of pixels and a second pixel located a second distance below the row of pixels;
• obtaining values of a set of pixel parameters for the multiple ones of the pixels, the set of pixel parameters including one or more color parameters and/or one or more image gradient parameters, the set of pixel parameters including a first pixel parameter, including obtaining a first value of the first pixel parameter for the first pixel and a second value of the first pixel parameter for the second pixel;
• classifying the multiple ones of the pixels as depicting a first feature or a second feature different from the first feature based on the distances and the values of the set of pixel parameters, including classifying the first pixel as depicting the first feature based on the first distance and the first value of the first pixel, classifying the second pixel as depicting the second feature based on the second distance and the second value of the second pixel;
• identifying one or more sets of pixels as depicting one or more boundaries between features based on the classifications such that a first set of pixels is identified as depicting a boundary between the first feature and second feature based on the classification of the first pixel as depicting the first feature and the classification of the second pixel as depicting the second feature;
• and
• effectuating an image effect on the image based on the identification of the first set of pixels as depicting the boundary between the first feature and the second feature.
