Slow feature action prototypes effect assessment in mechanism for recognition of biological movement ventral stream

Biologically-Inspired Computational Neural Mechanism for Human Action/activity Recognition: A Review

“…Kinetic-geometric models also used for modification of the methods involving "what" and "where" pathways and in general models with two separated pathways and improved form pathway (answer to "what"). Spatiotemporal filters often used to replace the MLD ( [15,16,38,39,[100][101][102][103][104][105][106]) and expanded into 3D structural methods ( [1,51]), even new deep learning approaches involving 3D recognition of human action (i.e., [99]). Table 1 summarizes the pros and cons of action recognition approaches.…”

“…A fuzzy-based optical flow proposed for dorsal streams was used to improve the model [100,101]. Furthermore, an approach to involve slow features was presented for ventral processing stream [16,103]. The active basis model [15] that applies Gabor wavelets (for the elements dictionary) consists of a deformable biological template.…”

“…where β = (β i , i = 1, ..., n) is set of Gabor Wavelet elements and components of sin and cosine, c i = I, β i and is unsolved image coefficient [15,103]. A Gabor wavelets dictionary, comprising n directions and m scales is in the form of, GW j (θ, ω), j = 1, ..., m × n. Where, θ ∈ { kπ n , k = 0, ..., n − 1} and ω = { √ 2…”

“…Optical flow is widely used in the computational model to provide motion information (i.e., the layer-wise optical flow) [15,16,38,[100][101][102][103]141,142]. M 1 and M 2 are visible masks for two frames I 1 (t) and I 2 (t − 1), and the field of flow from I 1 to I 2 and I 2 to I 1 are represent by…”

“…Moreover, a combination of slowly varying features and fast varying features proposed by Yousefi et a; (2016) [103]. Haghigh et al (2016) studied human-like movements processed in the human brain and motor control.…”
