A parking occupancy detection system includes a camera and one or more processors communicatively coupled to the camera. The one or more processors are collectively configured to receive an image of a parking region from the camera, wherein the parking region comprises a parking spot, extract an image of the parking spot from the image of the parking region, obtain an image descriptor value of the image of the parking spot, input the image descriptor value into a dynamic classification model, and classify the image descriptor value as occupied or unoccupied based on training data, wherein the training data comprises examples of occupied image descriptor values and unoccupied image descriptor values. 1. A method of detecting parking occupancy status , comprising: obtaining a plurality of parking spot training images, wherein each of the parking spot training images is associated with a known occupancy status;', 'obtaining a training image descriptor value from each of the parking spot training images, wherein each training image descriptor value is associated with the respective known occupancy status;', 'inputting the training image descriptor value and its associated known occupancy status into a dynamic classification model as training data; and', 'generating a parking spot occupancy classification rule through the dynamic classification model based on the training data., 'training a dynamic classification model, comprising2. The method of claim 1 , wherein the plurality of parking spot training images comprises at least one image a parking spot in an unoccupied state and at least one image of a parking spot in an occupied state.3. The method of claim 1 , wherein the image descriptor value is a histogram of oriented gradients claim 1 , pixel intensity claim 1 , pixel red-green-blue values claim 1 , pixel hue-saturation-value values claim 1 , a general histogram claim 1 , or any combination thereof.4. The method of claim 1 , further comprising:obtaining a parking ...
