1. A system for altering a perspective of an image, the system comprising: an image processing module, implemented using at least one hardware processor, for: obtaining a selection of a type of perspective reduction, the perspective reduction gradually narrowing a perspective of the image corresponding to a selected side of the image; rotating an image from an original orientation to an intermediary orientation based on the selected type of perspective reduction, wherein the intermediary orientation comprises one of: 90 degrees clockwise from the original orientation for a left-side type perspective reduction, 180 degrees from the original orientation for a bottom-side type perspective reduction, and 90 degrees counter-clockwise from the original orientation for a right-side type perspective reduction; removing one or more pixels from each of a plurality of rows of the image while the image is positioned in the intermediary orientation, where a quantity of pixels removed from a row of the image is based on a location of the corresponding row in the image; and rotating the image back to the original orientation after removing the one or more pixels.
