Left half-block

The code for the left half-block is as follows:

def create_left_half_blocks(bottom, bottleneck, hglayer, num_channels):# create left half blocks for hourglass module# f1, f2, f4 , f8 : 1, 1/2, 1/4 1/8 resolutionhgname = 'hg' + str(hglayer)f1 = bottleneck(bottom, num_channels, hgname + '_l1')_x = MaxPool2D(pool_size=(2, 2), strides=(2, 2))(f1)f2 = bottleneck(_x, num_channels, hgname + '_l2')_x = MaxPool2D(pool_size=(2, 2), strides=(2, 2))(f2)f4 = bottleneck(_x, num_channels, hgname + '_l4')_x = MaxPool2D(pool_size=(2, 2), strides=(2, 2))(f4)f8 = bottleneck(_x, num_channels, hgname + '_l8')return (f1, f2, f4, f8)

The preceding code performs two specific actions:

• It defines the filter coefficients (f1, f2, f4, and f8) with resolutions ...
