WebOct 5, 2024 · The Haar–PHOG feature is a development of both HOG and PHOG based on Canny edge detection. One of its advantages is that PHOG feature conducts calculation in four different frequencies of LL, HL ... WebThe D-Haar features are derived in the subspace spanned by these basis vectors. Let the extracted Haar feature vector introduced in Section 2 be Y ∈ RN, where N is the dimensionality of the Haar feature space. PCA is firstly performed to solve the high dimensionality problem. The covariance matrix is:

WebThe D-Haar features are derived in the subspace spanned by these basis vectors. We then present an accurate eye detection approach using the D-Haar features. Experiments on Face Recognition Grand Challenge (FRGC) show the promising discriminating power of D-Haar features and the improved detection performance over existing methods. Haar-like features are digital image features used in object recognition. They owe their name to their intuitive similarity with Haar wavelets and were used in the first real-time face detector. Historically, working with only image intensities (i.e., the RGB pixel values at each and every pixel of image) made the task of … See more A simple rectangular Haar-like feature can be defined as the difference of the sum of pixels of areas inside the rectangle, which can be at any position and scale within the original image. This modified feature set is called 2-rectangle … See more One of the contributions of Viola and Jones was to use summed-area tables, which they called integral images. Integral images can be defined as two-dimensional lookup tables in … See more • Haar A. Zur Theorie der orthogonalen Funktionensysteme, Mathematische Annalen, 69, pp. 331–371, 1910. See more Lienhart and Maydt introduced the concept of a tilted (45°) Haar-like feature.
