A system and method for inline object detection using hue saturation value. One method includes determining, with an electronic processor running a single object classifier, a hue saturation value range. The method includes receiving a digital image including an object. The method includes detecting, without reloading the single object classifier, a macroblock from the digital image, the macroblock associated with the object. The method includes determining a target region within the macroblock. The method includes determining a quantity of pixels in the target region having a hue saturation value within the hue saturation value range. The method includes, when the quantity of pixels exceeds a threshold, completing object classification of the macroblock.
