Selective quality light field operations efficiently manipulate a multi-resolution representation of a light field. These operations include intra-image and inter-image decomposition and compression of a light field to a multi-resolution representation. These operations also include intra-image and inter-image decompression and reconstruction of a light field at selective quality. These selective quality operations also apply to storage, rendering, and transmission. Various techniques improve spatial displacement estimation of a prediction light field image from a reference light field image. These techniques includes constraining the placement and size of a search window based upon a geometrical relationship between prediction and reference light field images, hierarchical spatial displacement estimation, edge extension of a reference light field image, differential coding of displacement vectors, and multi-predictor spatial displacement estimation. Configuring reference and prediction light field images in view of geometrical relationships between light field images also improves spatial displacement estimation.
