- face detection, key point location, image normalization, and feature extraction can be collectively referred to as face feature template extraction. The following is a brief description of each step.
- Face detection refers to detecting whether a human face is in a captured image or video.
- the specific position of the face is calibrated to obtain a candidate face area.
- the Haar feature +adab 00S t algorithm can be used to achieve accurate positioning of the face position in the small gesture of -30 30 degrees in the image.
- Key point positioning refers to the position of the key point such as the eyes and mouth of the face on the acquired image (video) candidate face area.
- image projection can be used to obtain candidate eye and mouth regions
- the Haar feature +adaboost algorithm is used to obtain accurate eye center coordinates in the eye region
- the gabor feature and the adaboost algorithm are used in the mouth region to obtain accurate mouth corner coordinates.
- image normalization is to obtain a face template of the aligned effective area, and to eliminate the interference of external factors such as illumination, which is divided into pose normalization and illumination normalization.
- the normalization of the pose is based on the obtained eye and mouth position, and the original image is deformed to a standard face template by normalizing operations such as cropping, zooming, and posture correction, ensuring that the eyes and the mouth are in a standard position.
- Illumination Normalizes the image to be de-illuminated.
- Feature extraction is the extraction of features on the size and illumination normalized image, including Gabor local features, and LBP
- the face feature template alignment is to determine the similarity between the two sets of feature templates of the candidate.
- face verification the similarity between two sets of feature templates exceeds the set threshold for verification, that is, the two sets of feature templates are determined to be similar; in face recognition, the maximum similarity exceeds a given threshold for identification. And the face ID corresponding to the maximum similarity is the recognition result.
- the description of the specific example above is only for the implementation of the face visual search service in one of the prior art methods. According to actual needs, the face visual search may also be implemented by any other possible method in the prior art. Service, not to repeat here.
- the process of detecting the object and identifying the object image by the object visual search service may be performed in a manner existing in the prior art.
- the object visual search service may include three stages of image feature extraction, feature matching, and geometric verification. The following is a brief description of each stage.
- SIFT feature Scale-invariant feature transform
- SIFT features can maintain the invariance of image rotation, scale scaling, illumination changes and other factors, and maintain good stability for viewing angle changes, affine transformation, noise and other factors.
- the extraction of SIFT features can be achieved by the following steps:
- the extreme value detection of the scale space is performed.
- the original image is convoluted by Gaussian difference function DOG (Difference Of Gaussian) with different scales.
- DOG Difference Of Gaussian
- the image pyramid is a common group, each group has an S layer, the first layer of each layer of the image from the original image and different scales (the adjacent layer scale differs by a scale factor k) Gauss
- the nuclear convolution is obtained, and the next set of images is downsampled by the previous set of images.
- the DOG pyramid is subtracted from the adjacent Gaussian image pyramids.
- each sampling point in the DOG pyramid should be compared with 8 adjacent points of its same scale and 9*2 points corresponding to the upper and lower adjacent scales, if the sampling point The value is less than or greater than its 26 neighbors, then the point is a local extrema point (called a key point).
- the main direction of the key point When determining the main direction of the key point, it is sampled in the neighborhood window centered on the key point, and the histogram is used to count the gradient direction of the neighborhood pixel.
- the gradient histogram has a range of 0 360 degrees, of which there are 36 columns for every 10 degrees.
- the main peak (maximum peak) of the histogram represents the main direction of the neighborhood gradient at the key point, ie the main direction as the key point.
- this direction In the gradient direction histogram, when there is another peak corresponding to 80% of the main peak energy, this direction is considered as the secondary direction of the key point.
- the key descriptor When generating the key descriptor, first rotate the coordinate zero direction to the main direction of the key to achieve rotation invariance. Then, take the 16*16 window centered on the key point, calculate the gradient direction histogram of 8 directions on each 4*4 small block, and calculate the accumulated value of each gradient direction to form a seed point.
- Each key point can be described using 4*4 total of 16 seed points, so that 128 data can be generated for a key point, which ultimately forms a 128-dimensional sift feature vector.
- the sift feature vector has removed the influence of geometric deformation factors such as scale change and rotation.
- the feature vector is length normalized to further remove the influence of illumination variation.
- the feature vector of the key point is calculated closest to which leaf node of the hierarchical vocabulary tree (only kL sub-point product calculation is performed), and the feature vector can be quantized into a vocabulary.
- a picture can be represented by a document vector.
- Each dimension of the document vector corresponds to a visual vocabulary, and its value indicates how important the visual vocabulary is to the document.
- TF-IDF term frequency- Inverse document frequency, word frequency - inverse document frequency
- the degree of similarity between the query image and the object image in the database that is, the distance (L1 distance, L2 distance, cosine similarity, etc.) of the two document vectors in the vector space can be used.
- an inverted index (Inverted Index) is created for all object images in the database, that is, with a vocabulary number as an index, which database image numbers corresponding to each vocabulary are recorded, and vocabulary The number of occurrences in these database images, the matching process becomes the process of voting for the database images containing the query picture vocabulary.
- the first s candidate object pictures that are most similar to the matching picture are selected and returned as the result of the feature matching stage.
- the geometric verification process When performing geometric verification, it is the s candidate object images that are sorted in the feature matching stage, and the geometric position information of the feature points is used to further accurately match the query image.
- the nearest neighbor algorithm is used to calculate the point-to-point matching relationship between the query picture and the database picture, and the RASANC algorithm (Random Sample Consensus) is used to filter the mismatch points (outside points) that do not conform to the affine transformation constraints from the matching point pairs.
- RASANC algorithm Random Sample Consensus

- the service is not mentioned here.
- the process of detecting the text content and identifying the text content by the text visual search service may be performed in a manner existing in the prior art.
- the text visual search service may include the following stages of text detection, layout analysis, area binarization, area line segmentation, character segmentation, character recognition, etc., where:
- Text detection refers to the location of the text block obtained from the image by using the connected domain analysis
- Layout analysis refers to the division of an input document into regions of the same attribute, usually including graphics, images, tables, and texts. For text, it is also necessary to determine the direction of the text;
- the area binarization refers to the processing of the area obtained by the layout analysis.
- the horizontal text type can also be considered to perform binarization of the image;
- the regional line segmentation refers to the detection and classification of the connected body, the horizontal projection of the partial connected body, the division of the text area into sub-areas, the detection of the multi-row sub-areas, and the use of the connected body merging method to realize the line cutting of the multi-row sub-areas. Dividing, finally cutting the connected body between the lines, and classifying the small connected body into the associated text line according to the distance information;
- Character recognition means that the character text is extracted by the multi-mode Euclidean distance classifier through the feature extraction of the character image, thereby recognizing the text result of the character.
- the client may select a client that can perform positioning, and when the client sends an image recognition cloud service request to the server, the location information of the location where the client is located may be simultaneously (for example, latitude and longitude information, etc.) is sent to the server side, and when the server side returns the classified visual search result to the client, other related information can be given based on the positioning information at the same time.
- the location information of the location where the client is located may be simultaneously (for example, latitude and longitude information, etc.) is sent to the server side, and when the server side returns the classified visual search result to the client, other related information can be given based on the positioning information at the same time.
