Blockiness

Blockiness refers to the visual effect or perceived characteristic where an image, object, or surface appears to be composed of distinct, often square or rectangular, individual blocks. This often arises due to low resolution, aggressive compression techniques (especially in digital media), or deliberate artistic choices. blockiness can manifest in various forms, from pixelation in digital images to the perceptible seams in a physical mosaic. The level of blockiness perceived can depend on factors like viewing distance, the nature of the material, and the sensitivity of the observer. The effect generally detracts from a smooth or realistic presentation.

Blockiness meaning with examples

• The low-resolution video suffered from significant blockiness, making it difficult to distinguish individual features and creating an unpleasant viewing experience. The compression algorithm used prioritized file size over image quality, resulting in large, noticeable pixel squares. Viewers were often distracted by the obvious, jerky transitions in the picture. This blockiness, even caused some scenes to look like a mosaic.
• The close-up photograph of the building facade revealed an unwanted level of blockiness. Each individual brick was clearly defined, and the mortar lines were pronounced. The result was a slightly crude aesthetic, diminishing the overall visual appeal of the scene. The lack of detail at this level of magnification accentuated the blockiness of the design. Even at a distance, the texture was a little too pronounced.
• When zoomed in on the digitally painted character, an unwanted blockiness became apparent. The brushstrokes were overly simplified, creating a rigid and unnatural form. The lack of subtle gradations in color and shading contributed to the pronounced visual artifact, which detracted from the perceived realism of the render. The original painter should have added some blur or anti-aliasing.
• The architect deliberately incorporated blockiness into the design of the building, using large, modular concrete blocks. The result was a strong, geometric aesthetic intended to emphasize the structure’s solidity and modern minimalist style. He wanted to give a sense of the design's ruggedness and strength. The pronounced blockiness, contrary to the norm, was considered a desirable attribute.
